Wells are currently not permitted and therefore Seward currently does not have any specific code around wells. Septic systems are currently permitted in city limits under certain conditions. Other municipalities allow wells and septic systems under certain conditions, including Anchorage and Soldotna, whose code is included in this packet. Anchorage has a comprehensive well code and permitting process for wells. Along with the Seward septic system code, Anchorage and Soldotna point to and rely on the Alaska Department of Environmental Conservation (DEC) for their regulations. Anchorage has additional requirements, as well. Alaska DEC Minimum Separation Distance Requirements for Wells (2.6) An excerpt from the Alaska Department of Environmental Conservation explaining the minimum distance required between drinking water sources and potential sources of contamination like septic systems. Fire Department Summary (3.1) The Fire Insurance/ISO Rating information is summarized. The Fire Suppression Rating Schedule factors are described in detail. Allowing housing development in areas where we don’t have fire hydrants could negatively impact the rest of the community’s insurance rates. The applicable portions of International Fire Code (IFC) are listed, including the allowance of in-home automatic sprinkler systems if hydrants are not present. Currently in the City of Seward, hydrants are spaced every 500’. In Soldotna, because of 2012 IFC, they are still required to have hydrants every 400-600’ depending on the development, even those areas on wells and septic systems. The Fire department enclosed information about how fast fires move/grow and their estimated response time to those situations for perspective. They do have mutual aid agreements with both Lowell Point and Bear Creek Fire Departments in which their tanker trucks could be accessed. They do not recommend purchasing a tanker truck as they are expensive and don’t have a place to store it (indoors). Attorney Summary (3.2) The city would not have liability if there were not fire hydrants in the area. That being said, the city does require there to be in home sprinkler systems if hydrants aren’t available. If the city 2 chooses to allow wells there are a number of issues and questions the code would need to specifically address and answer. Community Development Summary (3.3) If the council chooses to allow wells, there will need to be code implemented that considers both lot size and distance, as the placement of a well in conjunction with a septic system could heavily impact the development of a neighboring property. Maps Properties without Utilities Summary (4.0) There are a series of maps outlining the areas in Seward without utilities. Some of these properties are developable and some are not due to geography. For Forest Acres Information (5.1-5.2) The map shows the lots that were in the improvement district in recent years along with a cost breakdown by lot size for water, sewer, electricity, and roads. If the plat restriction were removed (see below) and wells were allowed, the property owners would still need to do an assessment district for electricity and improved roads. Estimated cost to install a well and septic are around $25,000 total. Plat Restricted Lots (5.3-5.5) These documents show the properties in Forest Acres that have a plat restriction of no septic systems and the process for getting that restriction removed if the property owners chose to do so.

Prior to the transfer by gift, deed or contract of any ownership or use interest in a privately owned on-site water well, the transferor shall obtain a certificate of on-site systems approval from the development services department. 1. The requirements of this subsection A. do not apply to transfers between spouses, or to a family trust. B. Upon request and subject to the provisions of this section, the development services department may issue or deny the issuance of a certificate of on-site systems approval for any dwelling or site served by a privately owned well. C. Where an on-site well does not conform to state and/or municipal laws, but no material health hazard is posed by postponing correction of the well's defects, the development services department may issue a conditional certificate of on-site systems approval to extend the period of time for corrective action until weather conditions allow. This conditional certificate may be issued with conditions necessary to ensure the public health and safety are not endangered. D. The development services department shall issue a certificate of on-site systems approval if the department finds information provided by an engineer demonstrates the system for which the certificate is sought conforms to all applicable provisions of chapter 15.55, regulations promulgated hereunder and applicable state statutes and regulations in effect at the time of original installation or at the time of any subsequent modification and does not presently create a health hazard. 13 E.

For other contaminants, including arsenic and nitrate, the departments shall use current USEPA public drinking water standards as a guideline to trigger actions deemed necessary to protect the public health. If nitrates are present greater than 10.0 mg/l, the applicant shall comply with subsection H., below. H. If sampling results from a well on a property requesting a certificate of on-site systems approval show the nitrate concentration in the well water is greater than 10.0 mg/l, the following steps shall be taken: 1. A visual inspection of the well bore, using a down hole camera, performed by a certified well driller or pump installer, or engineer shall be used to evaluate the integrity of the casing and the well is cased, without perforations, to the required depth. 2. An evaluation of the annular seal around the well casing shall be performed by a certified well driller, pump installer, or engineer in accordance with procedures established under subsection F. Fluorometric dye and water shall be introduced into a temporary basin dug into the ground surface surrounding the well casing stick up. Well water samples for laboratory analysis shall be collected for a minimum of 48 hours after dye is introduced and analyzed by a certified laboratory for the presence of the dye. Presence of the dye within 48 hours is evidence of an inadequate annular seal around the well casing. The annular seal shall be deemed satisfactory if dye cannot be detected within the first 48 hours of introduction. 3. If the annular seal around the casing is determined satisfactory through dye testing, the development services department may issue a certificate of on-site systems approval provided the well is cased and un-perforated to a minimum depth of 40 feet and meets all other well code construction standards in place at the time the well was originally constructed. If the well does not meet the minimum 40 feet easing depth, at the time approval is requested from the development services department, a certificate of on-site systems approval may be issued if the well is retrofitted with a pressure- grouted well liner installed to a minimum depth of 40 feet. 4. If water producing zones with greater than ten mg/l nitrates are found below the well casing and there are also other water producing zones with less than ten mg/l nitrates, the well shall be retrofitted to eliminate cross connection between the water producing zones. 14 5. If the well casing or annular seal around the casing are determined to be inadequate or unsatisfactory, or if cross connections between water producing zones are found, the well shall be repaired or modified to meet current well construction standards outlined in section 15.55.060 or the well shall be decommissioned in accordance with section 15.55.060L. After the well is brought up to applicable standards, the development services department may issue a certificate of on-site systems approval. The development services department may require additional monitoring. 6. Upon completion of any rehabilitative well work, the temporary basin created around the well casing for the dye test shall be filled with a bentonite slurry and re-graded to meet the standards in section 15.55.060C.2. The well shall also be disinfected in accordance with section 15.55.060G.1. and retested for nitrates.

Prohibited wells. Well pits are prohibited. The development services department may, at its discretion, allow an existing well pit to remain in use if it is shown the pit provides adequate protection against flooding. B. Well location and minimum setbacks. The location of a well shall be at a site readily accessible year round for testing, repair or maintenance purposes. The minimum separation requirements between wells and other specified facilities or areas shall be: TABLE A-1 EXPAND SEPARATION OF WELL FROM: MINIMUM SEPARATION DISTANCE IN FEET Private sewer line 25 Curtain drain 25 Petroleum Hydrocarbon storage tank 25 Sewer trunk line 75 Any other source of potential contamination 75 Holding tank 75 Septic absorption field 100 Sewer manhole or cleanout 100 Septic tank 100 Animal containment areas 50 Manure/animal excreta storage areas 100 15 C. Well drilling. The commercial drilling of a well and subsequent rehabilitation or deepening operation shall be performed by a licensed well driller. Any drilling method used in the construction of a well shall meet the following requirements: 1. The well driller shall notify the development services department of the proposed date of commencement of any drilling or rehabilitation or deepening or decommissioning operation prior to the start of operation. 2. The ground surface surrounding the well for at least ten feet shall be sloped or contoured to allow surface water to drain away from the well. 3. The well driller shall exercise reasonable care during excavation or drilling operation to prevent contamination to any aquifer. 4. Organic drilling fluid may be used only if the fluid is approved for such use by the National Sanitation Foundation (NSF) or by an equivalent organization; these fluids are listed in NSF Standard 60 and NSF Standard 61 and in associated product listings described in these two standards. 5. Water used in the drilling process shall be obtained from a source providing potable water. 6. Water wells shall be drilled and cased with non-perforated pipe to a minimum depth of 40 feet, in unconsolidated materials and in bedrock. If bedrock is encountered at a depth greater than 20 feet and less than 40 feet, then the easing shall extend a minimum of 20 feet into the bedrock. Where it is necessary to case bedrock to meet these requirements, an oversized borehole shall be drilled from surface to the required depth into the bedrock. The resulting oversized borehole shall be grouted in accordance with section 15.55.060D.2. 7.

Department Input 3.1 Fire Department Seward has adopted, with some exceptions, the International Fire Code (IFC) for fire prevention. The information below includes: Fire Insurance/ISO Rating Fire Suppression Rating Schedule (FSRS) Overview 2021 International Fire Code Hydrant Distance Information Fire Response Protocols and Timelines Fire Insurance/ISO Rating ISO-Insurance Services Organization-Grades are 1-10 with a 10 essentially no fire department and a 1 being the highest grade. We are a 3/3Y which is exceptional for a town our size. They grade us as a whole; they do not care about zoning or districts other than SMIC is considered an independent classification due to it’s remoteness from the city hence the “Y” signifies. If we take on areas of the city with buildings and do not provide hydrants, then that is putting the rest of the community’s insurance rates at jeopardy. The Fire Suppression Rating Schedule (FSRS) Overview The Fire Suppression Rating Schedule (FSRS) is a manual containing the criteria we use in reviewing the fire prevention and fire suppression capabilities of individual communities or fire protection areas. The schedule measures the major elements of a community’s fire protection system and develops a numerical grading called a Public Protection Classification (PPC®). Our FSRS employs nationally accepted standards developed by such organizations as the National Fire Protection Association (NFPA), the American Water Works Association (AWWA), and the Association of Public-Safety Communications Officials (APCO) International. When those organizations update their standards, the evaluation changes as well. The PPC program always provides a useful benchmark that helps fire departments and other public officials measure the effectiveness of their efforts — and plan improvements. How the FSRS works The FSRS lists a large number of items (facilities and practices) that a community should have to fight fires effectively. The schedule is performance based and assigns credit points for each item. Using the credit points and various formulas, we calculate a total score on a scale of 0 to 105.5. 28 To receive certain PPC ratings, a community must meet minimum criteria. After a community meets those criteria, the PPC rating depends on the community’s score on the point scale. For more information, see: Minimum Facilities and Practices to Get a PPC Rating Minimum Criteria for Class 9 Minimum Criteria for Class 8B Minimum Criteria for Class 8 or Better Scores and PPC Ratings The FSRS considers three main areas of a community’s fire suppression system: emergency communications, fire department (including operational considerations), and water supply. In addition, it includes a Community Risk Reduction section that recognizes community efforts to reduce losses through fire prevention, public fire safety education, and fire investigation. Emergency Communications A maximum of 10 points of a community’s overall score is based on how well the fire department receives and dispatches fire alarms. Our field representatives evaluate: the emergency reporting system the communications center, including the number of telecommunicators computer-aided dispatch (CAD) facilities the dispatch circuits and how the center notifies firefighters about the location of the emergency Fire Department A maximum of 50 points of the overall score is based on the fire department. We review the distribution of fire companies throughout the area and checks that the fire department tests its pumps regularly and inventories each engine and ladder company’s equipment according to NFPA 1901. We also review the fire company records to determine factors such as: type and extent of training provided to fire company personnel number of people who participate in training firefighter response to emergencies maintenance and testing of the fire department’s equipment Water Supply A maximum of 40 points of the overall score is based on the community’s water supply. This part of the survey focuses on whether the community has sufficient water supply for fire suppression beyond daily maximum consumption. We survey all components of the water supply system. We also review fire hydrant inspections and frequency of flow testing. Finally, 29 we count the number of fire hydrants that are no more than 1,000 feet from the representative locations. Community Risk Reduction The Community Risk Reduction section of the FSRS offers a maximum of 5.5 points, resulting in 105.5 total points available in the FSRS. The inclusion of this section for “extra points” allows recognition for those communities that employ effective fire prevention practices, without unduly affecting those who have not yet adopted such measures. The addition of Community Risk Reduction gives incentives to those communities who strive proactively to reduce fire severity through a structured program of fire prevention activities. The areas of community risk reduction evaluated in this section include: fire prevention fire safety education fire investigation 2021 International Fire Code Chapter 5, (Fire service features) of the IFC, Section 507.5.1, (Where required) is revised to required. Where a portion of the facility or building hereafter constructed or moved into or within the City is more than 250 feet (76.20 meters) from a hydrant on a fire apparatus access road, as measured by an approved route around the exterior of the facility or building, on-site fire hydrants and mains shall be provided where required by the building 507.1 Required Water Supply. An Approved water supply capable of supplying the required fire flow for fire protection shall be provided to premises on which facilities, buildings or portions of buildings are hereafter constructed or moved into or within the jurisdiction.

Hydrant Distance Information City of Seward fire hydrants are spaced every 500 feet (500’). Soldotna is on 2012 IFC and has no provisions, exemptions, or changes to Chapter 5, so hydrants are required every 400’ or R-3 (single family dwellings) every 600’. Fire Response Timelines and Protocols Mutual Aid Agreement with Bear Creek and Lowell Point The City of Seward has Automatic and Mutual aid agreements with Lowell Point and Bear Creek. That is dependent on whether their apparatus are not on another call, down for maintenance, or otherwise unavailable. They also must respond from their respective stations 31 which adds time to the response. The City of Seward should not look at buying a tanker, they are expensive for just a small portion of town that does not, or would not, have hydrants and we have nowhere to house another piece of apparatus. Response Time: Time is of the essence. We are short staffed mostly volunteer fire department. Volunteers have to respond from home, get the fire truck, respond, catch a hydrant, set up the fire truck for operation, pull hand lines, then fight the fire. See below where we are in the response window of 6-8 minutes if we are lucky. Moment Zero: Ignition In this example, we’re going to look at a fire that begins on the stovetop. Nearly half of all house fires start here, and all it takes is a few seconds for a pot to boil over, spilling oil-laden contents onto the burner, where leftover fat or residue is able to catch fire – in just a few hundredths of a second, no less. First 30 Seconds: Once a flame occurs, fire is able to spread easily. Any splattered grease, fat, or residue on the stovetop will ignite, and any combustible materials (i.e. paper towels, paper or cardboard packaging, potholders, or dish towels) will begin to heat up, smolder, and burn. This introduces deadly smoke to the mix. At this point, extinguishing the fire with an appropriately-rated fire extinguisher, or smothering the flames to deprive them of oxygen is crucial. Remember to never use water on a cooking fire, as it can spread the flames. 30 Seconds to 1 Minute: If the fire goes unnoticed after the first 30 seconds, it will grow higher and hotter. Both exposure to open flames and radiated heat will cause more combustible materials to set on fire, and it will continue to spread around the entire room. The larger the fire grows, the larger a plume of hot air and smoke that will rise up to and across the ceiling. 60 Seconds to 2 Minutes: During this time, the hot plume of smoke is beginning to grow thicker and deeper beneath the ceiling, thus increasing carbon monoxide levels. It will quickly begin to spread outwards into hallways and adjacent rooms and will even begin traveling through the vents. 2 Minutes to 3 Minutes: By now, the kitchen cabinets, wooden shelves, and countertops are being consumed by the fire. With so much combustible material being on fire, the temperature in the upper layer of hot gas 32 reaches 400 degrees Fahrenheit – hot enough to kill a person. The smoke is now dense enough that it is hanging just above the floor, and it is growing increasingly toxic. 3 Minutes to 4 Minutes: It only takes 3.5 minutes for the heat from a fire to reach 1100 degrees Fahrenheit. Because this level of heat can cause all materials in the room to spontaneously catch fire, flashover occurs during this period of time. This means that everything is engulfed in flames and the oxygen is sucked out of the room, causing glass windows to shatter. Flames pour out of doorways and start to burn ceilings and walls, thus traveling to other areas of the home at a rapid speed. 4 Minutes to 5 Minutes: Now, flames can be seen from the street, and the chance of escape or rescue may be impossible. The collapse of wooden floors and even the roof is inevitable. We have a full-blown house fire. The speed with which flames can grow, spread, and engulf an entire home is incredible, but being aware of the power of fire can help you prepare safe evacuation routes for yourself and your loved ones, and to practice fire safety throughout your household. Water Flow Information Fire flow = length X width ÷ 3 This formula is most easily applied if the estimated square footage of the entire structure is used to determine an approximate fire flow for the total structure and is then reduced accordingly for various percentages of fire involvement. The example shown below would illustrate how the formula can be applied to a single-family dwelling 60 feet long by 20 feet wide and one story high: 60 X 20 ÷ 3 X 1 (floor) = 400 gpm 100% involvement = 400 gpm 50% involvement = 200 gpm 25% involvement = 100 gpm The quick-calculation formula indicates that if the dwelling were fully involved, it would require 400 gpm to effectively control the fire. If only half of the building were burning, 200 gpm would suffice, and 100 gpm should be sufficient if one-fourth of the building were involved. Multi-Story Structures 33 In multi-story buildings, if more than one floor in the building is involved in fire, the fire flow should be based on the area represented by the number of floors actually burning. For example, the fire flow for a two-story building of similar dimensions as the previous example would be: 60 X 20 ÷ 3 X 2 (floors) = 800 gpm if fully involved If other floors in a building are not yet involved but are threatened by possible extension of fire, they should be considered as interior exposures and 25 percent of the required fire flow of the fire floor should be added for exposure protection for each exposed floor above the fire floor to a maximum of five interior exposures. (A fire on the first floor would threaten the second floor and 25 percent should be added. A second-floor fire would probably not threaten the first floor, so no interior exposure would need to be calculated). Exterior Exposures Likewise, if exterior structures are being exposed to fire from the original fire building, 25 percent of the actual required fire flow for the building on fire should be added to provide protection for each exposure. The following example shows how to apply calculations for exposures to our previous one-story dwelling with two separate exterior exposed structures: 60 X 20 ÷ 3 X 1 = 400 gpm 2 exposures: 400 gpm X (25% X 2) = 200 gpm Total fire flow required = 600 gpm (for 100% involvement of the original fire area). If the exposure becomes involved in fire (either additional floors of a multi-story building or adjacent structures), the exposure(s) should then be treated as a separate fire area and calculated separately, then added to the required fire flow for the original fire area. In using the quick-calculation method to determine required fire flows, it is important to remember that the answers provided by this formula are approximations of the water needed to control the fire. The formula is geared to an offensive attack and its accuracy diminishes with defensive operations. Don't forget that you are estimating both the area of the building and the amount of fire involvement within the building. Since firefighting is an inexact science to begin with, the use of the quick-calculation formula cannot be expected to determine the exact gpm that will be specifically required for full fire control. It has been found that as the amount of involvement reaches a stage where a defensive attack is necessary, the needed fire flow will be found to be slightly greater than required. Seward Engine-2 carries 750 gallons and Engine-4 carries 1000 gallons. Just one nozzle flows 150gpm. That means pulling one attack line, there is 5 minutes of water flow, which is insufficient to extinguish a well-involved structure fire. 34 3.2 City Attorney and Staff Sam Severin, City Attorney The question from council, as I understand it, is whether the city has liability if it allows wells, which would then make for less fire hydrants or fire hydrants being farther away from residences. This is compounded by concerns about lack of a tanker truck at the fire department. The simple answer is no, there is no liability. I could have answered that spontaneously but am glad I paused. Kody had gone pretty far down the Quitberg argument previously. He explained that IFC 507, which is adopted in SCC 9.15.111, requires sprinkler systems in homes if there isn’t a fire hydrant within a certain number of feet. That is the practical answer. There is already a built-in alternative. The more lawyerly answer - -by-day operation [ ] of the [municipal] There is a whole statutory scheme on this and a body of caselaw that explains it. The example I use often is police. The city can decide not to have a police department. That is no problem at all. If someone gets hurt and sues the city saying a police department would have prevented it, suit gets dismissed. City could just decide tomorrow that having the department is just a waste of money and that it would rather focus on sidewalk repair. No problem. But once it does have a police department, it must operate the department “non-negligently.” Here, the city is free to decide that it wants to do a scheme that involves less fire hydrants. The decision would allow for development and is backstopped by the sprinkler requirement. So, it is within the realm of a reasonable policy decision. Now, if the city decides to have hydrants, there is some burden. For example, if someone struck a hydrant with a vehicle and the city knew it was broken, it would need to fix the hydrant. That is an “operational issue.” Otherwise, there might be liability. But the decision to allow wells, would be at the policy level, not the operational level. Thus, the city enjoys immunity. There is one caveat – a very obvious one. I am not aware of a state law dictating number of fire hydrants per capita or anything like that. I looked, and I highly doubt there is such a thing. We can just double check that one more time. Kody has a number of concerns he pointed out to me regarding wells in the city. They kind of get into the engineering side of it – concerns that would likely be better addressed ultimately by an engineer, but questions that should be asked. Alex has also been kicking this around with us, so anyone feel free to chime in here. Alex Foote – Staff Attorney I agree with Sam. For a description of the general principals Sam described, I find the case Barton v. City of Valdez, 504 P.3d 910 (Alaska 2022) illustrative (some excerpts are included towards the end of this email). 35 I have not identified any statutory requirement for a specific number of hydrants per capita or area. It appears Alaska law contains specific provisions generally precluding liability in such situations. For instance, AS 09.65.070(c) limits liability for claims of negligence against firefighters acting in their official capacity: “[a]n action may not be maintained against an employee or member of a fire department operated and maintained by a municipality or village if the claim is an action for tort or breach of a contractual duty and is based upon the act or omission of the employee or member of the fire department in the execution of a function for which the department is established.” In terms of liability for not providing hydrants in certain areas, AS 09.65.070 appears to again limit claims for this type of decision: “(d) An action for damages may not be brought against a municipality or any of its agents, officers, or employees if the claim (1) is based on a failure of the municipality, or its agents, officers, or employees, when the municipality is neither owner nor lessee of the property involved, (A) to inspect property for a violation of any statute, regulation, or ordinance, or a hazard to health or safety; (B) to discover a violation of any statute, regulation, or ordinance, or a hazard to health or safety if an inspection of property is made; or (C) to abate a violation of any statute, regulation, or ordinance, or a hazard to health or safety discovered on property inspected; (2) is based upon the exercise or performance or the failure to exercise or perform a discretionary function or duty by a municipality or its agents, officers, or employees, whether or not the discretion involved is abused; [or] (3) is based upon the grant, issuance, refusal, suspension, delay, or denial of a license, permit, appeal, approval, exception, variance, or other entitlement, or a rezoning…” Additionally, while the following Alaska Supreme Court case has been criticized in intervening years, it appears to remains good law, and is in accord with the statutory protections contained in AS 09.65.070: City of Fairbanks v. Gilbertson, 16 Alaska 590, 1957 WL 3596 (Terr. Alaska 1957)(“A municipality is under no obligation to provide a fire department to protect the property of its residents, and hence is not liable for… failure to provide adequate fire fighting equipment, or failure to provide adequate water supply to extinguish fires”). From my perspective, in the absence of a statutory requirement regarding the number, type, or location of hydrants, the city would no more incur liability for deficiencies regarding same than a city that chose not to post a police officer on every street-corner. General Discussion of Discretionary Function Immunity from Barton v. City of Valdez, 504 P.3d 910 (Alaska 2022) “[T]he dividing line between planning and operational decisions may often be hard to discern.” Because “almost any act, even driving a nail, involves some ‘discretion’ ... decisions made while 36 implementing a planning decision are not necessarily unprotected operational decisions.” The distinction “depends on the particular circumstances” of the case.” “We recently applied this framework in Haight v. City & Borough of Juneau. In Haigh, ta teenager died in a motorized watercraft accident on Auke Lake, which was managed in part by the municipality. The teenager's mother sued the municipality, claiming that it negligently failed to take measures to ensure the safe operation of motorized watercraft on the lake. The municipality claimed that it was protected from suit by discretionary function immunity. We agreed. We concluded that “not regulating lake safety was a planning decision protected by discretionary function immunity” because it “involved basic policy considerations regarding allocation of scarce resources and which uses to allow.” We also considered whether the municipality had nevertheless assumed the duty to regulate lake safety. Observing that state law did not require the municipality to regulate lake safety and that the municipality's own ordinances and land use plans did not address lake safety, we concluded that the municipality had not affirmatively assumed the duty to regulate. For that reason the municipality was immune from liability for its lack of safety regulation at the lake: “Unless dictated by a plan or regulation, the decision not to act is fundamentally discretionary, as are its consequences, because scarce resources mean that not every possible course of action can be funded and because of the threat of unpredictable and overwhelming liability.” “We have held multiple times, for instance, that the State's decision to not install a guardrail is one of policy. We similarly have found that decisions on whether to install sequential stop lights or traffic safety devices were policy decisions and not operational ones. By contrast, once a decision is made to abate a particular hazard, the decisions involved in implementing that policy are typically deemed operational. In State v. Abbott we affirmed a decision that the State was not entitled to immunity for inadequately sanding an icy curve despite a policy of “work[ing] overtime if necessary to keep sharp curves well sanded.” We reasoned: Once the initial policy determination is made to maintain the highway through the winter by salting, sanding and plowing it, the individual district engineer's decisions as to how that decision should be carried out in terms of men and machinery is made at the operational level; it merely implements the basic policy decision.” Kody George – Staff Attorney I think Alex and Sam addressed the liability question well. My thoughts weigh in towards a different question that follows: if the city were to allow wells, what kind of legal scheme should be adopted? From Alex’s research, it is clear that liability can be incurred at the operational level once the policy is decided, so building a good framework for the policy is key to preventing liability once it’s adopted. Some considerations from other entities’ well codes: 37 1. Many other well codes are housed in the “public health and safety” sections. What public health implications could allowing wells introduce that should be addressed in code? a. Will the drawdown allow for saltwater intrusion on the City water system or freshwater supply? b. Are there any potential contaminants (Arsenic is a notable one) that the code would need to require testing for? c. Would the City require any periodic testing or proof of operation? d. If taken to the extreme position (i.e. every property allowed to have a well installs a well) would there be any water supply issues? Any other foreseeable issues? e. Will the City require setbacks from septic systems or wastewater lines? f. Fire safety has been addressed somewhat below. Additional question is if the City would want to adopt any other/additional fire safety measures to protect against inability of fire department to adequately fight fires? 2. Will allowing wells increase any other operational costs for the City? What are the financial impacts now and ten years from now? Will those costs be adequately recaptured through the code or permit charges? 3. To reasonably change this policy, does the City need any additional studies or information such as a city wide water assessment? 4. Is there a way the City can shape either the code or permitting process to adequately address all of its concerns so as to limit liability when it implements the changed policy? These questions aren’t meant to be a deterrent if the City wants to change its policy. I’m asking them now because these are the types of things we will want to know when we perform a review of the ordinance at the end of the line so that the policy is well thought through and can be shaped in a way to limit liability as Alex describes below. 38 3.3 Community Development Our initial thought was to prefer allowances by lot size versus zoning district. Upon further research, if the City goes this route, it might be better to view this in the realm of distance vs. lot size. Included in Section 2.7 is the Alaska DEC minimum separation distance required for wells. Our recommendation is to adhere to these guidelines. However, using these guidelines still leaves the question of how (if there is a desire to do so) would the City handle the coordination between neighbors concerning where septic tanks and wells are placed. For example, you need 100 feet distance between your well and any septic tank. That may be easy to do on one property, but if you put your septic tank within 100 feet of your property line, then you are impacting where your neighbor can put a well. This problem isn’t solved with a minimum lot size, and it becomes more challenging to coordinate with neighbors for small lots. Language in Title 14 would be needed to address how the City would deal with those specific situations. 39 Properties without reasonable access to City water and sewer Context Map Map 1 & 2 Map 3 Map 4 & 5 40 Properties without reasonable access to City water and sewer Map 1 4.1 Maps of Properties without Utilities 41 Properties without reasonable access to City water and sewer Map 2 4.1 Maps of Properties without Utilities 42 Properties without reasonable access to City water and sewer Map 3 4.1 Maps of Properties without Utilities 43 Properties without reasonable access to City water and sewer Map 4 4.1 Maps of Properties without Utilities 44 Properties without reasonable access to City water and sewer Map 5 4.1 Maps of Properties without Utilities 45 46 $ 1,478,320.00 $ 1,258,660.00 $ 895,201.63 $ 213,179.51 $ 3,845,361.14 Lot ID Parcel ID Street Address Lot Size (Acres) Lot Size % of Total Project Water Service Sewer Service Roadway Service Water Improvements Cost (Weighted) Sewer Improvements Cost (Weighted) Electrical Improvements Cost (Weighted) Roadway Improvements Cost (Weighted) Total Cost Per Parcel 17 14531032 2505 Afognak Ave 0.82 4.32% X X X $63,902.08 $54,407.02 $9,214.93 $43,307.69 $170,831.72 18 14531033 2507 Afognak Ave 0.82 4.32% X X X $63,902.08 $54,407.02 $9,214.93 $43,307.69 $170,831.72 19 14531034 2509 Afognak Ave 0.82 4.32% X X X $63,902.08 $54,407.02 $9,214.93 $43,307.69 $170,831.72 20 14531035 2601 Afognak Ave 0.82 4.32% X X X $63,902.08 $54,407.02 $9,214.93 $43,307.69 $170,831.72 21 14531036 2607 Afognak Ave 1.41 7.43% X X X $109,880.40 $93,553.54 $15,845.18 $74,468.10 $293,747.22 CR 14503504 2505 Pine St 1.03 5.43% X X X $80,267.24 $68,340.53 $11,574.85 $54,398.68 $214,581.30 CQ1 14503506 103 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CQ2 14503507 2511 Pine St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CD 14503607 2502 Pine St 0.49 2.58% X X X $38,185.39 $32,511.51 $5,506.48 $25,878.99 $102,082.37 CF1 14503609 203 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CF2 14503610 207 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CP1 14503107 102 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CG2 14503208 206 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CP2 14503108 106 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CG1 14503207 202 Cottonwood St 0.48 2.53% X X X $37,406.09 $31,848.01 $5,394.10 $25,350.84 $99,999.05 CO 14503103 2605 Afognak Ave 1.03 5.43% X X X $80,267.24 $68,340.53 $11,574.85 $54,398.68 $214,581.30 CH 14503205 2605 Oak St 1.03 5.43% X X X $80,267.24 $68,340.53 $11,574.85 $54,398.68 $214,581.30 AX 14503308 2610 Oak St 1.01 5.32% X X X $78,708.66 $67,013.53 $11,350.10 $53,342.40 $210,414.68 AY 14503311 2611 MAPLE ST 1.01 5.32% X X $78,708.66 $67,013.53 $11,350.10 $0.00 $157,072.28 AZ 14503312 2607 Maple St 1.01 5.32% X X $78,708.66 $67,013.53 $11,350.10 $0.00 $157,072.28 BA 14503307 2608 Oak St 1.01 5.32% X X X $78,708.66 $67,013.53 $11,350.10 $53,342.40 $210,414.68 BC1 14503314 302 Cottonwood St 0.47 2.48% X X X $36,626.80 $31,184.51 $5,281.73 $24,822.70 $97,915.74 BC2 14503315 306 Cottonwood St 0.47 2.48% X X X $36,626.80 $31,184.51 $5,281.73 $24,822.70 $97,915.74 BD1 14503316 310 Cottonwood St 0.47 2.48% X X X $36,626.80 $31,184.51 $5,281.73 $24,822.70 $97,915.74 BD2 14503317 312 Cottonwood St 0.47 2.48% X X X $36,626.80 $31,184.51 $5,281.73 $24,822.70 $97,915.74 BE1 14503709 303 Cottonwood St 0.47 2.48% X X X $36,626.80 $31,184.51 $5,281.73 $24,822.70 $97,915.74 BE2 14503710 307 Cottonwood St 0.47 2.48% X X X $36,626.80 $31,184.51 $5,281.73 $24,822.70 $97,915.74 Total Cost of Improvements Total Cost of Electrical Improvements Total Cost of Roadway Improvements FOREST ACRES SPECIAL IMPROVEMENTS DISTRICT - WATER & SEWER FEASIBILITY STUDY COST APPORTIONMENT METHOD 2 CONCEPTUAL COST ESTIMATE Total Cost of Water Improvements Total Cost of Sewer Improvements 5.2 Forest Acres Utility Cost Breakdown 47 5.3 Forest Acres Plat Restricted Lots Map 48 5.4 Plat Note Removal Process: The Borough ultimately will approve or deny a request to remove a plat note.

These Best Management Practices (BMPs) were designed for Alaskans who use, provide access to, or otherwise have a vested interest in Al and quantity, with the intent of protecting our shared resource through proper construction, maintenance, and decommissioning of groundwater wells. In 2012 the DEC began facilitating meetings with participation from representatives of different stakeholder groups to identify and address issues and concerns related to groundwater protection in Alaska. This stakeholder workgroup consisted of water well drillers, pump installers, hydrologists, engineers, state agency (i.e., DEC and DNR) staff, public water system owner/operators, water testing lab professionals, as well as private citizens. Meetings were held on a roughly monthly basis during the relatively slow off season. Minutes and results from the meetings were regularly shared with a broader group through email and a meeting web page. The stakeholder workgroup thoughtfully developed BMPs over the course of approximately BMPs are intended to be applied to the construction of all non-public water wells and the maintenance or decommissioning of all wells and boreholes (public and non-public). The BMPs balance protecting groundwater and public health with practices that are economically sustainable and can be applied statewide. An additional outcome of the stakeholder workgroup meetings was a web site containing information compiled from across the state and nation as it relates to private drinking water wells, found at http://dec.alaska.gov/eh/dw/DWP/DWP_PrivateWells.html. The BMPs for maintaining or decommissioning all wells are intended to provide easy access to, and clarify, methods as they apply to Alaska, by serving as an alternate DEC-approved method as described in 18 AAC 80. Adequate protection of our groundwater resources relies on Alaskans recognizing its importance and can be accomplished through voluntary application of these BMPs.

All necessary authorizations/permits should be obtained before proceeding with the project. 3 Scope These practices apply to construction of non-public water system wells used as sources of water, and associated observation or test wells, within the state of Alaska, except for groundwater monitoring wells that are installed, maintained, and decommissioned in accordance with a work plan approved by the Alaska Department of Environmental Conservation (ADEC) Division of Spill Prevention and Response or the ADEC Solid Waste Program. Water wells constructed prior to the date of establishment of these Best Management Practices should not be reviewed based on the omission of, or failure to perform or meet, any of the recommended practices contained herein, unless at that time, those practices were stated and established in local or State of Alaska regulations. 4 Updates and Alterations Future changes to this document should be done after review and approval by a committee (similar to the original Groundwater Protection and Water Wells Stakeholder Workgroup) composed of representatives from the public, industry groundwater professionals, and appropriate state agency staffs. 5 Definitions The words, terms and phrases, used herein have the meanings given to them in for ALASKA BEST MANAGEMENT PRACTICES FOR MAINTAINING OR DECOMMISSIONING WATER WELLS AND BOREHOLES and ALASKA BEST MANAGEMENT PRACTICES FOR THE CONSTRUCTION OF NON-PUBLIC WATER WELLS , except where the context clearly indicates a different meaning. 6 Well Site Selection The location for the well should be considered prior to drilling in order to ensure adequate and sustainable quantity and quality. Due diligence should be applied to ensure the following considerations are taken into account: A. The well should be located in order to discourage ponding of water and contaminants near the well. B. The well should be placed in an area that is not susceptible to damage from vehicles and equipment. 75 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 2 of 11 6 (Continued) C. The well should be made visible from a close distance as to avoid damage and to be able to readily identify maintenance issues. D. Future access to the well by equipment needed for pump service or eventual well repair or decommissioning should be considered in well site selection. E. The minimum recommended separation distances between non-public water wells and other specified facilities or areas are listed in Table 1, below. When distances differ from federal, state, or local requirements, the greater distance should be used. Table 1.

Any well drilling method used in the construction of a well should meet the following requirements: A. The ground surface surrounding the well for at least ten (10) feet should be sloped or contoured to allow surface waters and contaminants to drain away from the well. B. The well driller should exercise care during excavation or drilling operation to prevent contamination to any aquifer. C. Drilling fluid may be used only if the fluid is composed of materials and additives which are NSF/ANSI approved. 76 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 3 of 11 7 (Continued) D. Water used in the drilling process should be potable water, if reasonably available, or water that will not result in a contaminated well. E. Water wells drilled or driven in unconsolidated formations should be cased with non- perforated pipe to a minimum of thirty (30) feet BGS, unless local areal experience has demonstrated that there is no water or no water suitable for potable use at greater depths. F. A well completed in unconsolidated formations should be constructed so water only enters the well from a single producing zone. G. Water wells that encounter bedrock shallower than twenty (20) feet BGS should be cased to a minimum of thirty (30) feet BGS and grouted to a minimum of 30 feet BGS per Section 7.K. The local areal experience exception from Section 7.E may apply for use of shallow water. H. Water wells that encounter bedrock at a depth greater than twenty (20) feet BGS and less than forty (40) feet BGS, should be cased a minimum of ten (10) feet into the bedrock. Where it is necessary to case bedrock, the cased borehole should be grouted in accordance with Section 7.K. The local areal experience exception from Section 7.E may apply for use of shallow water. I. In bedrock wells that utilize liners, the outer casing should be grouted per Section 7.K. The liner should have a formation packer set a minimum of ten (10) feet below the outer casing drive shoe if it is less than forty (40) feet BGS. The annular space should be grouted, using a high solids bentonite grout slurry (minimum twenty percent (20%) solids content) or granules, up to a minimum of five (5) feet above the outer casing drive shoe. J. The Federal Housing Administration (FHA) and the U.S. Department of Veteran s Affairs (VA) well construction standards for homes they finance require a minimum of forty (40) feet of well casing. K.Grouting.Grouting the outer annular space is necessary to prevent shallow non-potable groundwater or waters on the land surface from entering into a potable water aquifer. All wells should be grouted with bentonite grout slurry or granules as follows: 1. Using the dry grout method, from the pitless adapter level to at least ten (10) feet below the pitless adapter or, from the surface to a minimum twenty (20) feet BGS. 2. For drive-point water wells, grouting should be done using the dry grout method. 3. If bedrock is encountered as described in Sections 7.G through 7.I, the following grouting procedures should be followed: 77 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 4 of 11 7.K.3 (Continued) a. The permanent well casing should be grouted from the bottom of the borehole up using a high solids bentonite grout slurry (minimum twenty percent (20%) solids content) or granules. The oversized borehole should be stabilized to eliminate caving and sloughing. b. If the permanent casing is used as a tremie to place the grout by circulating from the bottom up, a minimum one (1) inch annular space from the bottom of the borehole to surface should be used if possible. c. If a temporary casing is used to stabilize the oversized borehole, it should be removed upon completion of grouting procedures. L.Well casing.All casing should be installed with materials in new or like-new condition, free of pits or breaks. 1. Polyvinyl chloride (PVC) and high-density polyethylene (HDPE) casing should be NSF/ANSI approved. 2. Drive-point water wells should be constructed with steel pipe per Table 2, below. 3. The minimum wall thickness listed in Table 2, below, should be used, and all casing greater than the nominal size of eight (8) inches should have a minimum wall thickness of at least 0.250 inches: Table 2.

Welded joints should be at least as thick as the thickness of the well casing and should consist of a minimum of two (2) welding passes. 78 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 5 of 11 7.L.4 (Continued) b. All glue bonding materials should be NSF/ANSI approved. 5.Well casing stick up.All well casing should extend a minimum of two (2) feet above the finished grade, with the ground sloped to drain away from the casing if possible, unless local conditions suggest a different height, less or greater but at least one (1) foot above finished grade, to protect the well from freezing or flooding. 6.Perforating or slotting.Perforating or slotting of the casing utilized for the purpose of allowing water to enter the well from producing zones encountered above the bottom of the casing should not extend higher than thirty (30) feet BGS. The local areal experience exception from Section 7.E may apply for use of shallow water. 7.Drive shoe.When the casing is driven or otherwise forced into the borehole, the bottom of the casing should be protected from damage by the use of a drive shoe. M.Well screen. Where geologic conditions are such that the well must be completed to draw from a sandy aquifer, or where greater water production is desired, installation of a well screen should be considered to control sand pumping by the production well pump. The commercial installation of well accessories should be performed by a well driller or pump installer and includes the following: 1. Premium quality well screens should consist of v-wire wrapped, welded construction, of stainless steel or plastic. 2. An accessory consisting of slotted PVC, HDPE, or steel pipe may be adequate. 3. The well screen assembly should include a minimum of two (2) feet of equivalent sized riser pipe topped with an appropriate well packer and having a closed bottom. 4. The slot or opening size should be selected to hold back at least the largest 30% to 50% of the aquifer grains, depending on the size uniformity of the aquifer grains. 5. Where formation material is extremely fine too fine for a well screen commonly used in Alaska, a pre-packed well screen or filter pack completion may be necessary. Those options are best utilized under the guidance of a groundwater professional. 6. Drive-point water wells should consist of stainless steel wire-wrapped construction and should be installed in locations as described in Section 6. N.Well disinfection.Wells should be disinfected as follows: 79 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 6 of 11 7.N (Continued) 1.New, rehabilitated, or deepened wells.Immediately after completion of drilling, rehabilitating, deepening, or servicing a well, the well should be disinfected. After the well is flushed of drill cuttings, apply a chlorine compound proportioned to provide a concentration of at least fifty (50) parts per million (ppm) as free chlorine to the entire volume of water in the well and borehole. The chlorine should be introduced into the well in a manner which should distribute it throughout the entire water depth. Allow the chlorinated water to remain in the well undisturbed for at least six (6) hours. 2.Hydrofractured well fracturing or redeveloped wells.While redeveloping or hydrofracturing wells, and when possible, a free chlorine residual in the well of at least five (5) ppm should be maintained. 3.Flushing. After the required disinfection time has elapsed, the well should be flushed of all chlorinated water before being placed into service. O.Well seal.If no further work is to be done on the well, the top of the casing should be closed with a sanitary well cap or watertight well seal of a type approved by the State and NSF/ANSI. P.Well identification. All wells should be labeled with a durable form of construction information upon completion. The construction information source should be secured to the well casing and contain the following information: 1. The name of the well driller, pump installer, and business affiliations; 2. The date the well was completed; 3. The total well depth; 4. The total depth of casing; 5. The location and type of well completion; 6. Static water level (SWL) below the top of the casing; 7. Well yield; and 8. Height of casing above finished grade. Q.Well log (Record of Construction) and as-built.The well driller should provide a well log to the owner within thirty (30) days of completion of the well. The well log is an important record that should be carefully filed and kept with other important property documents. To assist, a form is available from the Alaska Department of Natural Resources (ADNR),http://dnr.alaska.gov/, 907-269-8400. The well log should include at least the following pertinent information: 1. 2. Drilling fluid/circulation method; 3. The legal description and street address; 4. The method of drilling (rotary, cable tool, etc.); 80 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 7 of 11 7.Q (Continued) 5.

The name and address of the well driller; and 19. A description of the method of disinfection process used upon completion of the well. 8 Best Practices: Installation of Water Pumps for Non-Public Water Wells A.Pitless adapters.Pitless adapters should be installed by a pump installer, a well driller or by an excavator under the supervision of a pump installer or well driller. The burial depth and type of pitless adapter installed should be recorded on the pump install log. When installed, pitless adapters should be one of the types approved by NSF/ANSI. B.Well seal.The top of the casing should be closed with a sanitary well cap or watertight well seal of a type approved by the State and NSF/ANSI. C.Pump (aka well pump). The pump intake should be located beneath the maximum anticipated water pumping level at the maximum desired pumping rate and the pump should be sized to meet the maximum desired pumping rate and total dynamic head requirement of the water system. 1. If well capability does not meet the maximum desired pumping rate (which usually occurs during the peak water demand periods of 6:00 AM to 8:00 AM and 6:00 PM to 8:00 PM), additional water storage facilities and/or water use reduction measures should be considered. D.Riser pipe.It should be made of galvanized steel, PVC or HDPE. E.Well cable.It should be rated for water submersion and sized to safely accommodate the voltage, current flow, and distance from the pump motor to the power source. Submersible well cable is not suitable for underground burial. 81 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 8 of 11 8 (Continued) F.Well yield testing.Upon completion of a well, if the estimated producing rate assessed during drilling appears to be less than three (3) gallons per minute (GPM), a well yield test of adequate duration should be performed to verify the estimated long-term capacity, taking into account possible fluctuations due to seasonal differences or by other causes. The test should be performed by, or under the direction of, a groundwater professional using one or more of the following practices and by recording the following data measurements: 1. Bailing, air lift, submersible pumping, or recovery rate measurement procedures. 2. Record accurate measurements of the following: a. Well production or pumping rate (in GPM); b. SWL; c. Pumping water level or DD from SWL; d. Duration of pumping (elapsed time); e. Recovery rate; and f. Any other information useful in determining the estimated producing rate. 3. If at the time of the well yield test, the minimum estimated producing rate and/or recovery rate of a well is less than one-hundred and fifty (150) gallons per day (GPD) per bedroom of the household to be supplied, water storage facilities should be considered. If the non-public water well is to be used for purposes other than domestic determine the adequacy of the well for its intended use. G.Pump work.Upon completion of pump installation work, a chlorine compound proportioned to provide a concentration of at least fifty (50) ppm as free chlorine to the entire volume of water in the well and borehole should be applied. After chlorine is introduced, water should be circulated in the well so it reaches all parts of the pump equipment, inside and out. The chlorinated water should remain in the well for at least six (6) hours. H.Flushing. After the required disinfection time has expired, the well should be flushed of all chlorinated water before being placed into service. I.Pump install log (Record of Commissioning).The pump install log is an important record that should be carefully filed and kept with other important household documents. The pump installer or well driller should provide a pump install log to the owner within thirty (30) days of completion of the installation of a pump into a water well. The pump install log should include at least the following pertinent information: 1. 2. The legal description and street address of the property; 82 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 9 of 11 8.I (Continued) 3. The date of the pump installation; 4.pump installed; 5. The depth from the top of casing that the pump is installed; 6. The name and address of the pump installer, well driller or excavator; and 7. A description of the method of disinfection used. 9 Initial Water Sampling and Corrective Actions Water samples should be collected from the well and analyzed in order to establish baseline water quality as well as to identify potential water quality issues prior to putting the well into service. Sampling should be done by, or under the guidance of, a groundwater professional using a water testing State-certified laboratory. A.Water quality testing.Drinking water from the well should be properly sampled and subsequently analyzed for levels of total coliform, other bacteria, arsenic and nitrates. The levels of total coliform and other bacteria should conform to drinking water limits established in Alaska Administrative Code 18 AAC 80. For other contaminants, including arsenic and nitrates, the groundwater professional should use the current United States Environmental Protection Agency (USEPA) public drinking water standards as a guideline to trigger actions deemed necessary to protect public health. B.Water quality standards.Water used for domestic purposes should not contain concentrations exceeding the following ratios: 1. Total coliform 0 colonies per 100 milliliters (mL). 2. Other bacteria 10 colonies per 100 mL. 3. Nitrates 10 milligrams per liter (mg/L) 4. Arsenic 0.010 mg/L (10 micrograms per liter, g/L) C. If sampling results show the nitrate concentration in the well water greater than 10.0 mg/L, the following steps should be taken: 1. A visual inspection of the well and borehole, using a down-hole camera, performed by a groundwater professional should be used to evaluate the integrity of the casing and if the well is cased, without well perforations, to the total well depth or depth of obstruction. 2. An evaluation of the sanitary ground seal in the annular space around the well casing should be performed by a groundwater professional. 3. If producing zones with greater than 10.0 mg/L nitrates are found below the well casing and there are also other producing zones with less than 10.0 mg/L nitrates, the well should be retrofitted to eliminate cross-connection between the producing zones. 83 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 10 of 11 9.C (Continued) 4. If the well casing or sanitary ground seal in the annular space around the well casing is determined to be inadequate or unsatisfactory, or if cross-connections between producing zones are found, the well should be repaired or modified to meet current well construction practices or the well should be decommissioned in ALASKA BEST MANAGEMENT PRACTICES FOR MAINTAINING OR DECOMMISSIONING WATER WELLS AND BOREHOLES 10 Well Decommissioning Wells should be decommissioned ALASKA BEST MANAGEMENT PRACTICES FOR MAINTAINING OR DECOMMISSIONING WATER WELLS AND BOREHOLES 11 Important Considerations I aquifers and drinking water, it is highly recommended any action taken to construct a well follow the best management practices laid out in this document. If you reside in a municipality, borough, or other organized area, please check with your local government for any additional guidance, regulations, or requirements. A. Do not place, or allow the placement of, any refuse, trash, waste, or contaminated or hazardous substance into any existing or abandoned well or water source, and deter others from doing the same. B. The location of a well, on-site wastewater disposal system or subsurface drain, either separately or in combination with each other and other wells, on-site wastewater disposal systems or subsurface drains in the vicinity, should not have the effect of prohibiting future use of an adjacent lot or parcel. To ensure that the well is properly located with respect to the surrounding land owners, prior to installation of a well, obtain an agreement and necessary easements with the owner(s) of any affected adjoining property for the sharing of a well or other possible and unforeseeable problems. The agreement should be recorded and carefully filed and kept with other important household documents. C. Do not cause or allow the construction, installation or use of a cross-connection between a public water system and a non-public water system well, be it active, abandoned, or improperly decommissioned. D. Well pits should not be used in new construction in order to avoid the possibility of flooding and inadvertently contaminating the aquifer. It is important that existing well pits be properly maintained and have adequate protection against flooding. E. Free-flowing wells of any kind, whether by surface or underground discharge, cause water to be wasted and should be avoided and/or remediated. A high priority should be 84 CONSTRUCTION OF NON-PUBLIC WELLS Last modified: June 6, 2016 Page 11 of 11 11.E (Continued) placed on addressing and resolving any problem with free-flowing wells under the guidance of a groundwater professional experienced in the remedy of such conditions. 12 References (the most recent version should be referenced) Alaska Administrative Code 11 AAC 93, Water Management.
