Expecting her fifth child in October, the artist was further inspired to surround a male and female ptarmigan with five chicks. "Alaska summers are often a time when family comes to visit, gathering together to enjoy each other and beautiful nature," she said. That beauty includes Alaska's classic wildflowers forget-me-nots, fireweed, lupine —also featured in the painting. She said the painting also reflects her joy over being chosen to create the artwork. "I feel as though the baby I carry brings another blessinga chance to work with the railroad. This is my honor," she said. The happy news took her mind off some of COVID-19's grim impacts. Three years ago, this self-taught artist established a downtown art shop and gallery, Dreaming Bear Studiohttps://www.dreamingbearstudio.com/. Like so many businesses that rely on tourism, her gallery was hit hard by the pandemic. Yet, she remains grateful to customers who have come back to support her during this difficult time. Schaefermeyer originally hails from South Korea, where she met her husband Karl. In 2006, Karl brought Kwangsook to Alaska to settle in his hometown of Seward. The railroad's annual art print program began 43 years ago, when APPC commissioned renowned artist John Van Zyle to produce an official painting. Since that 1979 beginning, the annual tradition (except in 1984, when no painting was released) has evolved into a popular collector's item.

Pg. 24 INTRODUCTION During the mid-1970s, the City of Seward began developing a plan to create an industrial complex at the Fourth of July Creek area to service the maritime industry. The City annexed the valley in 1977, acquired lands through the Alaska Statehood Act Municipal Entitlement, and completed the 1979 Fourth of July Creek Industrial Development Feasibility Study. That study identified four examples of industries that would be more likely than others to locate in the Fourth of July Creek area: fisheries, shipyard, petrochemical processing, and heavy industry, such as ore refining and bulk freight handling. The foundation for the project was a shipbuilding facility proposed by the Danish firm Burmeister - Wain to meet the high demand for new vessels in the king crab fisheries. With the crash of the fish stock in 1980, the project evolved into a mix of ship repair facilities, general cargo, fisheries processing, and other industrial uses. The project today is essentially as described in the 1980 Century-Quadra report entitled "Fourth of July Creek Industrial Marine Park Project Description" and shown on Figure 2 - Project Overview and Figure 3 - Site Plan (Appendix Exhibits C & D). Upon completion of a comprehensive 1981 Environmental Impact Assessment, the City embarked on a multi -year construction project that ultimately invested the majority of the City's share of the port bonds and state oil revenues into: an access road, the relocation of Fourth of July Creek, a retaining dike, basin, breakwater, and shiplift. With a state grant, new investment work was done to the North Dock and a new floating dock for a total investment of approximately $65 million. Access, utilities, and land availability helped spawn development of the sawmill and the prison within the boundaries of the Fourth of July Creek valley complex. The shiplift has been operational since 1985, and a building was erected to cover large barges and vessels, new break room, and machine shop buildings. Development activity continues to occur in the area known as the Seward Marine Industrial Center (SMIC). In 1988, the Spring Creek Correctional Center was completed and was designated as a Level III (Maximum Security) Facility. Originally designed to house 412 long-term inmates, growth in prisoner population has dictated adding more bunks which gives a current population of over 500 prisoners. The facility is staffed with a team of more than 200 experienced correctional, administrative and management personnel and is a decentralized campus design, currently with three separate houses that are separated from the major administration/support complex by a large recreation/exercise field. Spring Creek Correctional Center is situated on a 328-acre site was made available by the Kenai Peninsula Borough and the City of Seward. THE PLAN GOAL: An action -oriented document to guide the City and private enterprise in completing the development of a vibrant and successful marine industrial center. The Seward Marine Industrial Center (SMIC) Development Plan is a direct outgrowth of the community's desire to enhance, encourage, and promote an atmosphere favorable for additional private sector economic development at SMIC. For the purpose of this plan, SMIC is considered to include the 128.5 acres immediately adjacent to the harbor basin, south of Spring Creek and west of the prison property (Tract A and Tract B, Johnson —Swift Subdivision, USS No. 1651, Parcel ID 14533004 [Appendix Exhibits A and B]). The SMIC Development Plan becomes a component of the City of Seward's Comprehensive Plan. Whereas the Comprehensive Plan contains both advisory and binding elements, the SMIC Development Plan contains only advisory elements comprised of goals, issues, and actions. The binding element of the Comprehensive Plan is the Land Use Plan which is a legal document that must be adhered to and can be revised only by ordinance. As part of the process of finalizing the SMIC Development Plan, the City solicited suggestions from various public boards and commissions and interested groups, such as the Seward Chamber of Commerce. The draft plan was presented to the public at advertised public hearings and through review by the aforementioned groups. The issues raised and recommendations made by those individuals and organizations are reflected in this document. The original plan was approved by the Seward City Council in 1995; it was updated in 2008, reviewed in 2011, and the most recent update was completed in 2018. An effective plan is one which is implemented. The City of Seward has a track record of accomplishing actions outlined in its plans. Recommendations from previous plans that have been accomplished within the SMIC area include: • Syncrolift with upland rail system • 315 ton Travelift • Bulk fuel facility • 430' North Dock • Fisheries dock and plant improvements Moving towards new ownership (Polar to Bornstein) • New DEC approved outfall • Electrical substation • Primary electrical service • 34 individual power stalls, water and sewer systems • Secondary sewer treatment plant • Preliminary real estate subdivision plat • Some fill and cargo laydown area 0 Some utility improvements, including area lighting LED High Mast lights • Campground improvements • Some real estate development (sales and leases) • 400 and 800 amp service at North Dock • Rubble mound breakwater • Wash down pad • 10 Ton crane • 315' floating dock (Fisherman's Float) • Building for wash down pad • Fenders on North Dock • Widen the 315 Ton Travelift and Travelift Pit Future plans to be considered and funded include: • Finish the heating system for the Wash Down Pad • New US Coast Guard facility BASIC MARINE INFRASTRUCTURE GOAL: Continue Upland development. BASIN The basin that was envisioned by the 1980 Century-Quadra concept was enclosed, protected and dredged to -21 feet mean lower low water (MLLW) to accommodate medium -draft vessels for ship repair, cargo off loading, and general moorage. The basin has been dredged to design with - 25 foot berths adjacent to the Shiplift Dock and the North Dock. The basin is protected by a rip - rap breakwater along the east shoreline, by a filled sheet pile cell breakwater along the south and southwest, and by sheet piling along a section of the North Dock. It is still open to Resurrection Bay along the west and northwest sides. Unlike a rock rip -rap breakwater, the gravel -filled interconnecting sheet pile cellular cofferdams making up the south breakwater require regular maintenance to prevent failure. • Monitor and repair South Breakwater anodes, as needed. DOCKS Docks described in the 1980 Century-Quadra concept included an inner dock along the north basin shoreline, deep -water sheet pile cell breakwater and dock enclosing the basin, a ship repair dock, a boat ramp, and other miscellaneous docks. A ship repair dock, small fish processing dock, barge ramp, and medium draft cargo dock have been constructed and are in operation. There is a growing demand for additional general purpose moorage dock space. (,rode,- „sift etie,, 4 t4is times Completed .. Vr .• 7 Completed • Surface the North Dock and staging areas with concrete, asphalt, crushed rock, or Roto- Mill (crushed asphalt) including the installation of drainage pipes. Part of the North Dock is paved. 0 The Barge ramp has been repaired and is being utilized. • Maintain the Fisheries Dock per lease agreement. Will be under new ownership soon. Completed The Shiplift Dock is maintained per a Maintenance and Operating (M&O) agreement with the Syncrolift lessee. • Repair or replace Syncrolift dock ladders, bumpering system and corrosion control of the pipe piling in the splash zone by application of a protective coating. • Monitor maintenance of the Shiplift Dock per M&O agreement for the useful life of the facility. SHIPLIFT OPERATIONS Shiplift Operations are divided between the mobile 315 ton Travelift and the 5000 long ton Syncrolift platform. The Syncrolift was an integral part of the original SMIC concept plan. The Travelift was purchased and put into operation by the City in 1990 and upgraded to a 315 ton Travelift in 2015 to fill the demand for lifting vessels too small to economically use the Syncrolift platform but too large for the City's 50 ton Travelift. A number of improvements relative to the 315 ton Travelift operation have been identified. Expand existing water and electrical systems in the boat storage area. Encourage the development of full -service work stations for major maintenance/ construction projects on vessels in order to limit the degree of maintenance allowed in the storage area. Provide additional restrooms, as needed. The Syncrolift, although owned by the City, is operated by a contractor through a Maintenance and Operating Agreement. UPLANDS The Uplands forming SMIC were for the most part created from the material dredged during the formation of the basin. The original design called for a grade of 18 feet above MLLW. The roads are to grade, but some of the land is below desired grade. Drainage ditches were placed along Delphin and Olga Streets and the north property line to divert water runoff in the summer. During winter, ditches and culverts freeze causing runoff to pool in the lower areas behind roads. Provide engineer -designed drainage. Fill and grade the storage area to the correct elevation for the continued improvement of drainage. Continuing the process. Add to Article 18 of all new leases, under Maintenance, "Do not push snow into ditches." MANAGEMENT GOAL: A management level that is responsive to the needs of its customers and users, adequately serves the public's needs, protects the City's investment, and ensures public safety. Security and concerns related to potential environmental pollution grow as the number of boats, cargo, and equipment on -site increases. Sufficient revenues are necessary for effective on -site management and security of this public facility. • Seek a rate of return from the use of public facilities, land assets, and equipment that will adequately cover deferred maintenance and replacement costs. - Examine electric rate method of calculating charges to users. - Examine credit card rate method of calculating charges to users. • Continue to review the Upland Boat Work Policy and Best Management Practices to ensure compliance with the Clean Water Act and Local, State, and Federal laws and regulations where they apply. • Ensure that the facility and uses are consistent with the requirements of the Maritime Security Act of 2002 33.CFR 104.105 and maintain the Facility Use Plan. 6 LAND USE GOAL: Sound, maximized, and coordinated development of private and public uplands and facilities in support of the needs of the users and visitors. PLATTING The City has formulated a subdivision of SMIC and the Fourth of July Creek Valley. The subdivision plat dedicates roads and provides as -built utility and access easements. It creates legal lots for existing leases and leaves the majority of the SMIC area in blocks. • Maintain an accurate map through survey and plat amendments for all current and future leases. LAND VALUES In order to provide adequate public services and maintenance at SMIC, it is important that the City receive a fair market value —the current rate is 8% annually of the appraised value —for the use of its limited land assets. Adjust the annual rental payment every five years. The adjusted annual rental payment shall be the appraised fair market rental value of the leased land at the highest and best use of the leased land. Lands were appraised in 2020; next appraisal due in 2025. Increase the annual rental payment every year in an amount that reflects the increase, if any, in the cost of living for the previous year as stated in the Consumer Price Index, All Urban Consumers, Anchorage, Alaska Area, All Items 1967100 ("CPI'), as published by the United States Department of Labor, Bureau of Labor Statistics. LAND USES SMIC is zoned Industrial. The Seward Zoning Code, Table 15.10.225 Land Uses Allowed, establishes what uses are allowed within that district. Uses allowed within the SMIC should focus on strengthening and enhancing the area as a center for marine and other compatible industries. • Review Table 15.10.225 to ensure the uses listed are compatible with the overall intent of the SMIC area. PARKS AND RECREATION Under State statutes, the City is required to provide public access along Spring Creek, Fourth of July Creek, and Resurrection Bay. Although the area is principally industrial, limited recreation opportunities can be made available without interfering with surrounding industrial uses. • Maintain access from Nash Road to the mouth of Spring Creek and provide a camping area, and include signage of the access route. Completed MARKETING GOAL: A comprehensive marketing program primarily targeting fisheries, ship repair, and marine transportation industries along with a healthy and complementary mix of commercial support businesses. Current City marketing efforts include: attendance at trade shows, overseas trade missions, brochures, and advertising. • Maintain a sign along Nash Road and central to the SMIC area showing what lands are available for lease (Appendix Exhibit E). • Maintain a fair market value base line from which leases will be negotiated. • Continue to encourage multiple users. • Evaluate utility rates to encourage more usage while ensuring a fair return to the public utility system. • Continue to support the Seward Chamber of Commerce as the marketing arm of the City of Seward. 9 TRANSPORTATION GOAL: An adequate transportation infrastructure that will serve the needs of the industrial complex, allow for growth, and attract new business to the community. ROADS Nash Road provides the only ground access to SMIC and the Fourth of July Creek area. To adequately serve SMIC and attract new industries, it is of the utmost importance to maintain and improve the public road system to the highest standard economically possible. • Postpone paving interior SMIC streets until site and utility developments are completed. PARKING Although parking has not been a problem in the past, as more activity develops it will become imperative that vehicles park in designated areas off public roads and away from equipment activity. • Ensure that all lease sites include adequate area to comply with parking requirements set forth in the zoning code, and that lessees provide on -site parking for employees and customers. • Maintain signage in parking areas in support of the public docks. AIRPORT Although not directly associated with SMIC, having a well -maintained airport is an important transportation link for the delivery of parts, goods, and services to the industrial center businesses. • Continue to work with the Alaska Department of Transportation and Public Facilities to improve airport facilities and protect it from river flooding and erosion. 10 PUBLIC FACILITIES & SERVICES GOAL: A full range of public facilities and services adequate to provide a safe and comfortable work environment for users and visitors. PUBLIC FACILITIES Public Facilities are currently limited from available to non -available. • Include construction of an additional public restroom/shower facility in the City's Capital Project Plan. • Improve paving, fill, fencing, and storm water drainage collection and treatment infrastructure as development occurs. PUBLIC SAFETY The distance from town limits police coverage to an occasional patrol and also increases fire response time. Although a pumper/ladder truck is located in the harbor storage building, there are no scheduled trained fire department personnel on -site to operate them. The fire truck is staged on - site and ready for volunteer personnel. • Evaluate each new development as to its impact on fire and police services. • Complete water system to loop all lines or upsize all cross -feeder lines and provide additional fire hydrants as needed. • Identify and reserve a site for a fire station to serve the Fourth of July Valley area. • Include a separate fire station in Capital Project Plan, to accommodate more and/or larger equipment and supplies to support increased industrial development. Possibly include a joint small office for Seward Police. • Explore possible cooperative arrangements with Spring Creek Correctional Facility staff to provide initial fire or other public safety needs. PUBLIC UTILITIES Public Utilities such as primary water, sewer, and electrical service systems have not been extended throughout the undeveloped SMIC areas (Appendix Exhibits F1-F3). The cost of extending these utilities creates a disincentive to the establishment of smaller businesses. • Improve the water and electrical systems in areas associated with the 315 ton Travelift to accommodate increased public use. • Include in City capital planning the extension of electrical, sewer, and water throughout the industrial area. • Support updating Seward City Code to facilitate utility extension development. • Continue to place all electric utilities below ground. is ENVIRONMENT & WASTE MANAGEMENT GOAL: A high level of environmental regulatory compliance and a clean work environment. ENVIRONMENTAL CONCERNS The objective of the City is to maintain a clean work environment and to protect the land, water, and air to the highest degree possible without making the area prohibitive for the type of activities associated with industrial areas. • Require compliance with all rules and regulations of the Environmental Protection Agency and the Alaska Department of Environmental Conservation. • Maintain policies and procedures for monitoring and ensuring vessel storage/ repair site clean-up. • Maintain and distribute use guidelines to lessees, operators, and users of the area for ship repair —including minor repairs, sand blasting, and painting. WASTE MANAGEMENT Waste Management is integral to managing a successful industrial area where large amounts of waste are generated. Separation of steel, wood, and general garbage is required at the Kenai Peninsula Borough (KPB) solid waste facility. It is illegal to dump used oil in solid waste containers. • Continue implementation and improvements of a program to control the separation, collection, recycling, and disposal of waste generated at the industrial center in accordance with established environmental policies and regulations/ requirements of the KPB solid waste facility. • Continue to improve used oil collection procedures and disposal facilities to meet the demands of user groups and to ensure a clean environment. • Improve methods to monitor waste material disposal to control and reduce the costs associated with the collection of solid and liquid waste materials. • Maintain a Storm Water Pollution Prevention Plan (SWPPP). im APPEARANCE GOAL: A high standard of aesthetic appearance and cleanliness through landscaping, litter control efforts, and development of public amenities that are in keeping with the industrial maritime theme of the area. LANDSCAPING & BEAUTIFICATION Industrial areas do not have to be barren and devoid of natural aesthetics. An atmosphere that is pleasant and attractive to users and visitors alike can be cultivated through thoughtful planning and landscaping efforts. • Where possible, reduce scrap metal storage, trash, and other materials that may be considered offensive to the casual observer. • Ensure that all businesses comply with City codes regarding the collection and disposal of trash. 13 SIGNS, ZONING, BUILDINGS GOAL: A high level of public and private compliance with Seward City Code. SIGNS Adequate public signing is important to provide directions, identify streets, point out public facilities, and post rules and regulations for visitors. Private signing identifies places of business. • Review public signing to ensure that it is adequate to the needs of the public and the City. • Ensure private signing meets Seward City Code. • Maintain a sign along Nash Road identifying and welcoming visitors to the Seward Marine Industrial Center. • Maintain a sign denoting lands for lease with contact information. • Support north and southbound directional signage to SMIC at the corner of the Seward Highway and Nash Road. Chamber of Commerce reported the state would not allow a sign for SMIC on the Seward Highway. ZONING Zoning code development requirements regulate open space for fire prevention/fighting, air and light. Recognize that current zoning codes could limit necessary and appropriate development, as proposed in Joint Overlays. Support variance requests for height and set -back requirements as approved by the Planning & Zoning Commission. BUILDINGS Buildings constructed to code are important to ensure safe working conditions and to add to the community tax base. The City has adopted building, fire, mechanical, electrical, and plumbing codes. • Ensure that all structures, permanent or temporary, are constructed to adopted building and fire code standards. 14 PLAN IMPLEMENTATION GOAL: Adoption of the plan by resolution of the City Council and implementation by all identified participants. For the City of Seward to realize the benefits of the SMIC Development Plan and thereby ensure sound growth and development, actions must be taken not only by the City of Seward but by many other players within the community and the Borough, State, and Federal Governments. Following are specific actions which are necessary to ensure the successful implementation of this Plan: Adopting a Plan shows commitment and establishes policy. Council should, by resolution, adopt the Plan based upon recommendations of the Port & Commerce Advisory Board and the Planning & Zoning Commission. Use the Plan to guide the City of Seward in the appropriate quality growth and development of the SMIC. Consistent with its original intent, the Plan will remain flexible. While it is intended that all actions presented in this Plan will be implemented, it is recognized that changing conditions in the future may necessitate modifications of planned actions or the introduction of additional actions to satisfy local needs. The City recognizes the critical role of plans as key program documents to guide the community's capital budgeting process. It is recommended that the SMIC Development Plan be reviewed annually and updated within five years, or more often as needed. An annual review will help track accomplishments, changes, and inadvertent omissions.

OPENING CEREMONY Board Member Benjamin Smith led the Pledge of Allegiance to the flag. ROLL CALL There were present: Bruce Jaffa, presiding; and Lynda Paquette Carl Hughes (telephonic) comprising a quorum of the Board; and Norm Regis, Harbormaster Brenda Ballou, City Clerk Excused — None Absent — None Vacant — Two Colby Lawrence Benjamin Smith CITIZEN COMMENTS ON ANY SUBJECT EXCEPT THOSE ITEMS SCHEDULED FOR PUBLIC HEARING — None APPROVAL OF AGENDA AND CONSENT AGENDA Motion (Paquette/Lawrence) Approval of Agenda and Consent Agenda Motion Passed Unanimous The clerk read the following approved consent agenda items: Approve the September 1, 2021 Regular Meeting Minutes. SPECIAL ORDERS, PRESENTATIONS AND REPORTS Proclamations & Awards — None Alaska Railroad Report. Christy Terry corrected the two bridge replacement items she noted in her report in the packet; the bridges being replaced were at Miles 24.4 and 25.7 over the winter. In addition, the railroad would be improving three communications sites between Seward City of Seward, Alaska Port and Commerce Advisory Board Meeting Minutes October 6, 2021 Volume 4, Page and Portage. She would be attending the Pacific Marine Expo in Seattle. She was still waiting for the developer/operator to be announced. The cruise ship schedule for 2022 had not changed and listed 99 cruise ships for Seward. Smith asked if the bridge replacements would be supported out of Seward or Anchorage. Terry said the crews would be stationed in Seward, so it would be a boost to Seward's economy. Jaffa wondered if there was an update on passenger trains. Terry stated there had been 57,859 passengers, which was not terribly far off from 2019. The expectation for next year, particularly if the cruise ships came, was to be high. In response to Paquette, Terry said a lot of train passengers could be correlated to an increase in day cruises in the bay; there was a strong partnership between the railroad and the water tour companies. Paquette asked about the status of the cruise ships that went to the southeast this year. Terry said the contingency plans for COVID mitigation were activated promptly and proactively, when necessary. Jaffa stated Chugach Electric released an announcement that their revenues were dramatically down due to COVID, and wondered if the railroad had similar concerns. In response, Terry said the railroad had received support from federal funds; the Coastal Classic passenger trains had not suffered. Terry added that another pipe ship was expected to arrive next month, and both freight and passenger activity was expected to be high next year. Jaffa commented that a local artist had been selected for the railroad's poster. Terry said there had been an in-house vote by railroad employees, and local Seward artist Kwangsook Schaefermeyer had been selected; there would be an artist signing at the Christmas Craft Fair this year. Chamber of Commerce Report. Jason Bickling said the new Small Business Development Center (SBDC) position for Seward should be posted this week and the posting would be wide -spread for at least two weeks. The chamber was in the midst of designing the layout for the new marine guide, and ad sales were underway for the visitors guide as well. In response to Paquette, Bickling confirmed that the chamber was fully staffed. Paquette asked for an update on the chamber lunches, and Bickling said there would be a virtual chamber lunch held on October 14, 2021. After that, lunches would resume in person, and sometimes there would be "After 5" events. Each lunch or event would include presentations followed by mix and mingle opportunities. Harbormaster Report. Harbormaster Norm Regis said one harbor admin staff member had resigned to take a dream job, and the position was currently being advertised. The bid deadline for the northeast launch ramp was extended to October 14, 2021. In response to Paquette, Regis said the contract for the cathodic anode replacement would go to council for approval on Monday. In response to Jaffa, Regis said the yard at SMIC was City of Seward, Alaska Port and Commerce Advisory Board Meeting Minutes October 6, 2021 Volume 4, Page getting full. Jag was currently working on the USCG Mustang, and had received the contract to work on a navy vessel. Other Reports and Announcements — None Presentations US Economic Development Administration (EDA) American Rescue Plan Programs presentation by Brandii Holmdahl. NEW BUSINESS Other New Business Items Review the schedule for the Alaska Municipal League (AML) Conference in November, determine attendees, and consider the potential impact on the November 17, 2021 PACAB work session. City Clerk Brenda Ballou explained that AML conducted a Local Government Conference every year in Anchorage, and she wanted to make all the boards and commissions aware that they could participate in the conference to receive training is they wished. In addition to the in person conference, AML would be holding a Newly Elected Officials virtual training. Regis pointed out that the conference dates coincided with PACAB's November 17, 2021 work session, and that he would be in Seattle that week for the Pacific Marine Expo. In response to Jaffa, Regis said in his absence, he would send another representative from the Harbormaster's office to attend the work session. Update on Interconnect Policy by Electric Utility Manager Rob Montgomery. Electric Utility Manager Rob Montgomery provided a laydown, stating it was the same information he had recently provided to city council. He participated in some Solarize Seward virtual workshops, and had collaborated with a vendor called Renewable Energy Systems on the installations of solar panels. Montgomery added that the city website for renewable energy interconnect had been updated, and now included a clear step-by-step guide. The webpage also linked to the city's interconnect application, which had been streamlined and was easy to complete. As well, Montgomery said the electric tariff had been updated to clarify definitions and calculation formulas. Montgomery recommended that residents do their homework to make sure they understood their options were so they were confident about their choices. Over the course of just this year, the Electric Department had increased the number of bi- directional meters from three to 15, and Montgomery expected to continue adding more throughout next year. City of Seward, Alaska Port and Commerce Advisory Board Meeting Minutes October 6, 2021 Volume 4, Page Paquette wondered what the impact on excess energy was having on the department's revenues. Montgomery said there was a minimum charge for all customers which covered the infrastructure. In response to Paquette, Montgomery said Chugach Electric had taken a revenue hit due to businesses closing from the COVID pandemic; large commercial spaces had been closed, and there was a marked increase in people working from home. Montgomery expected the potential of an increase in Cost of Power Adjustment (COPA), which was a pass -through charge to customers. Jaffa said Chugach had purchased Municipal Light & Power, which served more commercial accounts than residential; he thought that may have also had an impact on Chugach's revenues. Smith commended Montgomery for the increase in bi-directional meter installations. In response, Montgomery said Renewable Energy Systems was assisting customers with completing the applications. One of the critical considerations for the electric department in working with that vendor was to ensure the appropriate shut off protections were installed to protect workers. Paquette stated her understanding was that, if a customer had regular electric but wanted to go solar, they would contact the vendor, fill out the application, the city swapped out the meter and that was pretty much it. Montgomery concurred, and said sometimes lines needed to be moved, but Paquette had pretty well summarized the process. Paquette commended Montgomery on this accomplishment this year. Discuss pre -approved designs and net metering agreement. Jaffa stated that this item was covered in the discussion that just concluded. Review letter of support signed by Climate Action Committee representative and discuss next steps. Paquette had been engaged over the summer with climate change representatives from all municipalities across the state. The group was organized by the University of Alaska, and the result of the work by this group was a letter that was sent to US Senators Lisa Murkowski and Dan Sullivan, US Congressman Don Young, and the National Climate Task Force among others. The crux of the letter was that Alaska had a long history with the oil industry, but needed to move towards more environmentally friendly alternatives; the letter requested financial support. Paquette had provided her support for the letter because she was on PACAB's climate change committee, but thought she made it clear that she was not speaking for the entire city. Paquette wished to make the board aware of this exchange she had. She would have preferred to bring it to PACAB and council before submitting, but the timing did not allow. Paquette thought Seward had been awarded $40,000 to put towards education, but she didn't have that information with her. Paquette wondered what PACAB would be doing going forward with the own climate action committee. Jaffa recalled that PACAB's climate change committee consisted of himself, Paquette, and former chair Laura Schneider. Jaffa encouraged Paquette to stick with it, and to keep the board apprised of developments; if she could get more information about the funding, that would be good. City of Seward, Alaska Port and Commerce Advisory Board Meeting Minutes October 6, 2021 Volume 4, Page Smith appreciated Paquette keeping the board apprised of the activities; he cautioned that the scope of PACAB's role shouldn't be opened up too broadly. Smith said his wishes would be for Paquette to bring items and issues to the board, and allow the board to determine what they wished to pursue, to take action on themselves, or to bring forward to council. Jaffa concurred with Smith, and added that "port" and "commerce" could be interpreted many ways. Paquette said she would stick with it. Discuss the Formation of a Tourism/Hospitality Education Platform and Schedule a Work Session. Paquette said she had developed an outline for the board to consider for taking the next step to address developing a local program; there appeared to be a number of agencies and entities in the area that could potentially be pulled together to address this topic. Jaffa said he would be willing to create a committee along with Paquette, and perhaps one more member, to start working on this topic. Smith was a little unsure, but was willing to serve on the committee. Motion (Jaffa/Smith) Create a Tourism & Hospitality Committee consisting of Smith, Jaffa, and Paquette. Motion Passed Unanimous Discuss having a joint work session with the Historic Preservation Commission to review the draft of the Downtown Historic District Design Standards & Guidelines. Jaffa was not aware of this request. Ballou said there appeared to have been a breakdown in communication; at some point, the Historic Preservation Commission expressed a desire to review draft design guidelines for the downtown historic district with PACAB. There was a memo included in the September 1, 2021 PACAB meeting packet to this effect, but it was erroneously put under informational items in the back of the packet, and escaped notice. Ballou stated that when HP was ready to bring this forward to schedule a joint work session with PACAB, she would let PACAB know. On a separate note, Paquette wondered if the board wished to discuss the possibility of cancelling the November 17, 2021 work session, since it appeared that many people would be away at the AML Conference or the Pacific Marine Expo at that time. Lawrence stated he would be absent for both the November 3, 20221 PACAB meeting and the November 17, 2021 PACAB work session. Ballou stated that Hughes would be away through November. Paquette was confident that even though Lawrence and Hughes would be gone in November, the board would have new members. In response to Smith, Ballou said applications for new members that were submitted by October 19, 2021 would go to council for consideration in time for the November 3, 2021 PACAB meeting. City of Seward, Alaska Port and Commerce Advisory Board Meeting Minutes October 6, 2021 Volume 4, Page By unanimous consent, the board cancelled the October 20, 2021 work session; the board currently consisted of five members, and it was known that two members would be out of state at that time. INFORMATIONAL ITEMS AND REPORTS Port & Commerce Advisory Board Priorities (as approved by City Council). Port & Commerce Advisory Board 2021 Goals Calendar. CITIZEN COMMENTS — None BOARD AND ADMINISTRATION COMMENTS & RESPONSE TO CITIZEN COMMENTS Regis said Jag had the USCG cutter in for repairs, and the state ferry Aurora was being lifted today or tomorrow for repairs. The state ferry Tustemena would be repaired over the winter. Lawrence congratulated Montgomery on the success of the interconnect policy and implementation; citizens had been asking for this for a very long time. He thanked Brandii Holmdahl for providing the presentation today. Smith appreciated the presentation from Holmdahl as well. He noted this was the second meeting that AVTEC had been mentioned; AVTEC was under the Department of Labor and they offered a wide variety of training programs. Information about former graduates and upcoming graduates was available from AVTEC for any businesses wanting to seek new employees. Hughes thanked the board for the meeting today. Paquette appreciated Holmdahl's presentation. She was reminded again today about the lack of affordable housing in Seward; one of the hairdressers in town she knew had moved away because she couldn't find housing. Paquette looked forward to serving on the committee to examine the tourism and hospitality industry. Jaffa encouraged everyone to participate in PACAB and to get involved in the community. ADJOURNMENT The meeting was adjourned at 1:31 p.m. Brenda Ballou, MMC City Clerk (City Seal) Bruce Jaffa Chair rCRVV Technical Memorandum ENGINEERING GROUP, LLC Date: October 6, 2021 To: Doug Schoessler, DPW Director, City of Seward Thru: Morgan Welch, PE, R&M Consulting, Inc. From: Jon Hermon, PE — CRW Engineering Group, LLC Project: City of Seward WWTF Review Project (CRW# 77101.00) Subject: Review Summary Background The City of Seward has operated its wastewater treatment lagoon at Lowell Point since 1980. Since 1993, the lagoon has featured the two -cell configuration with which the City currently operates. Using this configuration, the City has been, with some particular exceptions, meeting its discharge permit requirements. The lagoons were drained to remove sludge in 2015 and then again in 2020 to repair aeration line breaks. Each time shortly thereafter, water quality and/or odor problems ensued. In the case of the 2020 event, the odor issue was exacerbated because one cell could not be refilled until the following spring after repair of the line breaks. The City has since addressed the odor issues with the filling and resumed aeration of the restored cell, the use of sodium nitrate and sludge -reducing bacteria (SRB). Lagoon Configuration and Operation The Lowell Point wastewater treatment facility (WWTF) treats wastewater generated by the entire city. The 2021 population of Seward is estimated to be about 2,850. However, the City has been using round -number estimates of 3,000 residents and 1,000 non-residents as the average daily number of users throughout the year. The user population tends to increase during the summer season, with an reported peak of around 20,000 users during the July 41h weekend. The City's sewer collection system conveys the regional wastewater to Pump Station 3, which is located at the beginning of Lowell Point Road on the southwest corner of town. From this lift station, the wastewater is pumped approximately 2 miles south to the lagoon system at Lowell Point. After treatment, the water is conveyed from the lagoon system northward, about % mile back up the road, to be discharged into Resurrection Bay through an ocean outfall. The lagoon features two aerated basins, each having a water volume of approximately 18 million gallons and a water surface area of about 3 acres. When at their maximum operating volumes, each basin has water depths ranging from 20 to 22 feet. The basins are separated by a bisecting concrete wall, to the top of which a floating baffle curtain is attached. Water flows through each basin from influent and to effluent pipes located at each end. Although the yard piping configuration allows the use of one or two basins, and a possible reverse flow condition, the aeration system is currently arranged such that wastewater needs to flow from the north basin to the south basin. The first (north) basin is aerated with a combination of 69 static tubes and 40 Biodomes, with 58 static tubes grouped relatively close together for aerating about 25% of the influent end of the first basin. The Biodomes aerate the back end of the first cell with the remaining 11 static tubes. The second basin is aerated with just 6 static tubes, with the assistance of two surface aerators, as needed. According to the Lowell Point WWTF O&M Plan, the facility uses two 40 HP blowers to supply air to the static tube aeration system. Each blower is capable of conveying 450 SCFM for a total maximum output Anchorage Office: 3940 Arctic Blvd. Suite 300, Anchorage, AK 99503 1 (907) 562-3252 fax (907) 561-2273 Palmer Office: 808 S.

A diesel -driven back-up blower can convey the same 900 SCFM output. The Biodomes are supplied with air by a 30 HP blower, each with a minimum of 2 SCFM. Assuming that the static tube aeration system is supplied by both blowers operating at full speed, and that the Biodomes are supplied with the foregoing flow rate, the estimated air supply rates to each aeration system are summarized in Table 1 below: Table 1— Estimated Aeration Capability System No. of Diffusers Unit Rate (SCFM) Total Rate (SCFM) Static Tubes 75 12.0 900 Biodomes 40 2.0 80 Total -- -- 980 The City is permitted to treat a maximum of 880,000 GPD (0.88 MGD). Other permitted effluent requirements are summarized in Table 2 below. BOD = biochemical oxygen demand; TSS = total suspended solids; DO = dissolved oxygen. On a scale of 0 to 14, pH refers to the degree of acidity (less than 7.0) or alkalinity (greater than 7.0) of the water, with 7.0 being neutral.

Based on Discharge Monitoring Reports (DMRs) shared by the City from Sept 2019 through mid -May 2021, the combined variability of various monitored parameters are summarized below in Table 3: 2 of 9 October 6, 2021 City of Seward WWTF Review Review Summary Table 3 - Variability of Currently DMR Parameters Influent Effluent BOD TSS Temp pH BOD TSS FC Ammonia DO Value FC/100 mg/L mg/L °C -- mg/L mg/L mg/L mg/L mL Avg 159 320 10.0 7.1 10.0 7.0 13,484 13.1 9.9 Max 370 658 20.0 8.0 43.0 24.0 101,000 34.0 14.8 Min 21.1 79.3 0.5 6.9 3.5 1.7 667 1.1 2.3 Std Dev (±) 84.0 149 6.5 0.1 7.3 4.8 18,016 9.4 2.3 "Greater than 243 469 -- -- 17.3 11.7 31,500 22.5 -- Avg." The City measures only effluent flow rates, the variability of which are summarized in Table 4 below, along with the associated hydraulic retention time in each of the two basins.

Since only effluent levels have been measured, estimated influent ammonia loadings are calculated based on typical concentration values for domestic wastewater (avg. 25 mg/L; max 35 mg/L; min 15 mg/L; std dev 4 mg/L). From these values, oxygen requirements in lb/day are estimated and shown in Table 5 below. These values are averaged over the volume of the entire lagoon. 3 of 9 October 6, 2021 City of Seward WWTF Review Review Summary Table 5 — Variability of Oxygen Requirements Total Total BOD TSS Ammonia-N Winter Summer Value Loading 02 Loading 02 Est. 02 Loading 02 Req'd Req'd Req'd Loading Req'd lb/day lb/day lb/day lb/day lb/day lb/day lb/day lb/day Avg 601 841 1,208 846 95 435 1,687 1,904 Max 3,703 5,184 6,585 4,610 350 1,611 9,794 10,639 Min 42 59 159 111 30 138 170 231 Std Dev M 113 158 200 140 5 25 298 318 "Greater than 714 999 1409 986 100 459 1985 2444 Average" To obtain the estimated oxygen requirements need to biologically stabilize BOD, TSS and ammonia, the following factors are used: • 1.4 lb of 02 per lb of BOD. This factor is a conventional amount used in wastewater treatment design. 0.7 lb of 02 per lb of TSS. This factor (assumed to be 50% of BOD 02 requirement) is conservatively used to estimate the additional oxygen requirement associated with TSS (such as algae) and sludge aging. This factor is not always used in oxygen calculations, but is used in this study as a consideration for treating additional oxygen demand generated as a result of long detention times in the lagoon cells (which favor algal growth and sludge aging). 4.6 lb of 02 per lb of ammonia -nitrogen. This factor is used to estimate the oxygen needed for nitrification, to convert ammonia (NH3) to nitrates (NO3). Nitrification is assumed to substantially occur only during the summer months when water temperatures are warmer. Use of this oxygen requirement amounts to the difference between the summer and winter total oxygen requirements shown in the table above. It needs to be noted that the total maximum and minimum oxygen requirements indicated in Table 5 above are extreme values, assuming that the maximum and minimum of the BOD, TSS and ammonia parameters occur on the same day. This type of occurrence is unlikely and shouldn't be used in the evaluation of the capabilities of the treatment process. Instead, the average values are reviewed with the standard deviation amounts added or subtracted. As a simplified way to characterize the variability of these parameters, the standard deviation calculation is used to provide a sense of how dispersed measurements within a data group are. Measurements falling within one standard deviation from the average are assumed to occur approximately 2/3rds of the data group timeframe. Relative to the maximum and minimum parameter values, these measurements therefore have a greater probability of occurring concurrently. Therefore, "greater -than -average" values of flow, TSS, BOD, fecal coliforms (FC) and ammonia are calculated as conservative amounts by adding the standard deviation to the average and summarized in the above table for oxygen requirements. "Less -than -average" conditions are 4of9 October 6, 2021 City of Seward WWTF Review Review Summary reflected in flow, TSS, BOD, FC and ammonia loadings less than the average conditions summarized above. Aeration Requirements The Lowell Point WWTF is assumed to have been originally designed as a "partial -mix" treatment system, meaning that oxygen is provided only for biological treatment and not for also keeping solids suspended (as would be the case in a "complete -mix' system). With a partial -mix system, solids will settle and accumulate at the bottoms of lagoon cells, where further treatment slowly occurs by anaerobic decomposition. In this manner, the lagoon system also functions facultatively, wherein both aerobic and anaerobic processes provide biological treatment. The first cell functions more aerobically than the second cell, which has substantially less aeration and functions more like a facultative lagoon. Based on the recent DMR data summarized above and using approximate calculations and depending on flow and wastewater conditions, it appears that the biological oxygen requirements can exceed the aeration capacity of the WWTF (980 SCFM—all blowers operating). If TSS and sludge are considered as oxygen demand generators, then aeration requirements more than double the amount of air needed without considering TSS. Ammonia is considered only for summertime conditions, when water temperatures are warmer for facilitating nitrification. For purposes of these calculations, the population of Seward is projected to increase by 4.5% in the next 10 years and 9% in the next 20 years. This would add approximately 130 to 260 persons, respectively, as year-round users. At 125 GCPD water usage per capita, this growth would add 0.016 to 0.032 MGD to the average influent flow and approximately 22 to 44 Ibs of BOD to the daily average. These calculations are summarized in Table 6 below for both the current timeframe and Year 2041 for projected, future average conditions. Conditions that appear to exceed the facility's aeration capability are shaded in orange/beige.

For greater -than -average conditions, the fine -bubble aeration requirement is nearly met within the air flow capabilities of the WWTF. • Except for the case where only the treatment of BOD is considered (i.e., wintertime operation without regard to any TSS and sludge -imposed oxygen demands), the treatment facility does not appear to have sufficient aeration capabilities for when flowrates approach the maximum permitted flow rate of 0.88 MGD, at average wastewater conditions. • Accounting for projected user population growth for the next 20 years, average wastewater conditions increase a minor amount and thereby impose a minor additional oxygen demand on the aeration system. With regard to meeting the DO discharge permit requirement for the mixing zone, the lagoon effluent receives a substantial amount of aeration as it freefalls several feet into the discharge piping of the flow control structure. This arrangement and continuing open channel aeration within the discharge piping 6of9 October 6, 2021 City of Seward WWTF Review Review Summary largely mitigates any effects in the mixing zone from deficient DO in the wastewater lagoon. Based on the DMR data, the City has for the most part been meeting the DO permit requirement. Discussion While the foregoing results indicate shortfalls in aeration capacity in various scenarios, they do not necessarily indicate that the facility's permit requirements will not be achieved, or that odors will ensue. Flowrates and organic levels entering the plant are constantly varying, and short-term surges can be readily attenuated in the large water volume of the two basins. Permit violations and odors become more likely when surges are prolonged (such as in a large, extended rainfall event), when overloading wastewater conditions happen concurrently (such as when high BOD, ammonia and algae levels occur at the same time during the summer), when contaminant conditions become chronic (such as the build-up of aging sludge) or if a prolonged loss or insufficiency of aeration occurred. Nevertheless, an aeration system that is capable of treating both short-term and long-term wastewater conditions will be an essential part of mitigating or avoiding permit and odor issues arising from significant events like the foregoing examples. The user population growth is anticipated to be slow for the foreseeable future, and flowrates and organic loading rates are expected to increase a relatively minor amount during this timeframe. However, as these rates slowly approach the aeration capacity of the WWTF, overloading conditions will be experienced more frequently. The results summarized in Table 6 and their associated conclusions reflect this potential. While the lagoon currently operates mostly around average conditions, for a significant degree of frequency, it approaches or exceeds greater -than -average conditions, and therefore approaches oxygen demands that tend to exceed the aeration capacity of the facility. These wastewater conditions would impact the aeration capacity as discussed below: The influent biochemical oxygen demand (BODs) is a constant condition and always present in various concentrations. The WWTF is configured to provide most of its aeration treatment capability in the first cell, and particularly in the front 25% of first cell's water volume. This approach intends to largely stabilize, mix and disperse influent wastewater as it enters the lagoon, leaving a lower oxygen demand as the wastewater migrates to the back end and into the second cell. During periods of high loading, it is suspected that the dissolved oxygen provided by the aeration system in this front zone is substantially consumed, leaving only low DO concentrations to enter the second lagoon cell. If sufficient BOD remains in the water entering the second basin, the aeration system of this cell could be overloaded a result. If prolonged, this condition would tend to produce anaerobic conditions in the wastewater and associated septicity and odors. TSS and sludge -related oxygen demands depend on the presence and concentration of BOD- producing TSS constituents (such as algae) and aging sludge. At high concentrations, algae can add significant amounts of BOD, although algae can produce oxygen as well. When algae die, interior substances disperse into the water and add to BOD. As previously mentioned, aging sludge also feeds soluble BOD and nutrients back into the water. The degree that BOD is augmented by these sources is dependent on how much is present in the lagoon system. The more BOD produced by these interior sources, the less effective the aeration system will be in treating influent contaminants. These conditions would tend to be more prevalent during summertime (when nitrification and denitrification is more active), at night time (when algae is undergoing respiration) and as sludge accumulates in the basins over the course of years. 7of9 October 6, 2021 City of Seward WWTF Review Review Summary Ammonia is normally present in raw wastewater and therefore always presents a potential oxygen demand. Nitrifying bacteria require oxygen and warm water temperatures to actively convert ammonia to nitrates in the nitrification process. During the winter, ammonia reduction typically becomes negligible. Further, with low DO levels, the nitrification process is substantially inhibited. To counter this condition, the Biodomes are designed to provide nitrification to some extent, the degree of which is uncertain for this study. Based on the measured ammonia levels in the effluent, it is presumed that only a limited amount of nitrification is provided by the Biodomes, or that ammonia is being fed back into the wastewater from aging sludge in the second basin. Nevertheless, with sufficient water temperatures and DO levels, the nitrification process will also impose a oxygen demand that must be addressed by the aeration system, as well as a demand on alkalinity. If the City is required in the future to minimize ammonia levels in its mixing zone, then the size of aeration system will need to be reviewed and modified as needed. While aeration provides a critical part in the biological treatment and mixing of wastewater, other processes are also involved in meeting the permit objectives. The relatively large water volume of each lagoon cell produces long detention times and accommodates slower biological treatment rates and a substantial amount of settling. It is likely that important contributions to the overall BOD and TSS removal at the WWTF is achieve through the settling of solids and anaerobically in the sludge blanket. However, these other mechanisms can eventually become detrimental. As sludge accumulations increase, the tendency for solids carry-over also increases, and the effluent water quality diminishes as a result. Other issues can result from sludge accumulations. As the sludge blanket ages, soluble BOD and nutrients are dispersed back into the water above, which imposes an additional oxygen demand on the treatment system. Denitrification can also occur in aging sludge blankets, which releases nitrogen gas and causes sludge to float to the water surface. Further, once or twice a year, the turning over of temperature -stratified water can cause sludge and associated by-products to rise to the water surface, causing strong odors. The accumulated sludge therefore needs to be reduced or physically removed from the basins, dewatered and disposed of on a regular basis. Doing so will appreciably complement the benefits of aeration, and in avoiding or mitigating acute and chronic events that can arise. Conclusions and Recommendations: The Lowell Point WWTF appears to be operating largely within its overall treatment capacity and will likely do so for the foreseeable future. However, it appears that the potential exists for its treatment capacity to be overloaded on a relatively frequent basis, when flow rates and organic loading rates are high, and when the oxygen demand is increased by nitrification and TSS-related sources. The City is encouraged to evaluate this potential in a more comprehensive effort. As this review is a relatively high- level evaluation, further considerations and assessments are recommended below to provide a more accurate understanding of lagoon conditions: Using a multi -function portable probe, perform summertime DO, pH and temperature measurement profiles in grid pattern from both lagoons during a period of non -rainy conditions and at least 3 days after a significant rain or high user population event. Collect and record measurements from at least the upper quarter depth, half depth and % depth of the wastewater. Ideally, measurements would also be taken from just above the sludge blanket and at a couple feet below the water surface. This effort will provide a good snapshot of the health of the lagoon wastewater when conditions will tend to be most taxing on the aeration system. 8of9 October 6, 2021 City of Seward WWTF Review Review Summary During the same effort, from at least four separate locations in each lagoon aeration zone (front and back zones of both basins), collect composite samples of BOD, TSS, carbonaceous BOD (CBOD), soluble carbonaceous BOD (SCBOD), ammonia, total Kjeldahl nitrogen (TKN), alkalinity, nitrites+nitrates. These tests will help discern the extent of nitrification and TSS-related oxygen demand sources. • Consider the eventual supplementing or replacement of the existing coarse bubble aeration system with a fine -bubble aeration system. With the ability to more efficiently oxygenate water, especially with the large water depth of the lagoons, subsurface fine -bubble aeration could sufficiently treat greater -than -average wastewater conditions for nearly the same energy requirements as the existing aeration system. Improved oxygenation will also reduce the tendency for odors, including the twice -yearly water turnover events during spring and fall seasons. • Consider replacing the existing blowers with new, more -efficient units having a higher aeration output to increase the capacity of the existing aeration system for improved treatment of greater -than -average conditions. Operate the blowers with variable frequency drives based on continuous DO measurements to improve power consumption. • Consider modifying the influent and effluent header piping to provide additional inlets and outlets serving each basin. Doing so would improve the mixing, dispersal and collection of wastewater to and from the lagoon basins, and reduce short-circuiting. The relatively large water volumes of the two basins tends to mitigate the effects of short-circuiting. • Continue implementing a regular sludge removal program. Consider the procurement of a floating dredge unit to reduce the need for dewatering the lagoon basins for this effort. • The use of sodium nitrate could continue to be used by the City as a relatively quick and temporary measure for addressing odors. This method does not appear to be a good permanent solution for proactively mitigating or preventing odors.
