Chapter 1 Overview and Certification

1-1 Background and Scope On November 16, 1990 (55 FR 47990), the Environmental Protection Agency (EPA) established regulations to control the amount of pollutants that accumulate in stormwater and discharge into waters of the United States. Facilities that discharge stormwater “associated with industrial activity” must comply with 40 CFR 122.26 and obtain a National Pollutant Discharge Elimination System (NPDES) permit.

The primary means to obtain an NPDES stormwater permit is through compliance with the Multi-Sector

General Permit for Stormwater Discharges Associated with Industrial Activity (MSGP). The State of

Alaska Department of Environmental Conservation (DEC) has been responsible for administering the permit since 2009. DEC issued a new MSGP permit (AKR060000) on 19 February 2015. The United

States Coast Guard (USCG) BASE Kodiak has elected to obtain NPDES stormwater permit coverage under this permit. The permit is designated as the 2015 MSGP in this document. The 2015 MSGP is included as Attachment A.

The 2015 MSGP is a broad-based pre-published permit that identifies actions necessary to achieve compliance. The permit specifies 30 industrial types of facilities (sectors) that trigger the requirement for permit coverage (i.e., if a facility engages in one or more of these 30 sectors they are “industrial” and permit coverage is required). Table 1-1 lists industrial operations conducted by BASE Kodiak:

Table 1-1 BASE Kodiak Industrial Activities Covered By the Multi-Sector General Permit Sector Sector Name Industrial Activities Covered

K Hazardous Waste Treatment, Storage, or

Disposal

Stormwater discharges associated with hazardous waste treatment, storage, or disposal facilities.

L Landfills and Land Application Sites Stormwater discharges associated with landfills.

P Land Transportation

Stormwater discharges associated with land transporting and warehouse facilities engaged in vehicle and equipment maintenance and equipment cleaning.

Q Water Transportation Stormwater discharge associated with water transportation facilities.

S Air Transportation Facilities

Stormwater discharges associated with air transportation facilities engaged in air transportation and airport and aircraft service and maintenance.

T Treatment Works Stormwater discharges associated with domestic wastewater treatment works.

Upon finalization of this SWPPP, BASE Kodiak will submit a Notice of Intent (NOI) to DEC to obtain permit coverage under the 2015 MSGP. Documentation that BASE Kodiak filed the NOI will be contained in Attachment A. This document will be modified when control measures are changed due to corrective actions or regulatory requirements.

BASE Kodiak leases a portion of its property to the Alaska Department of Transportation (AKDOT) for operation of the Kodiak Airport. Additionally, AKDOT subleases certain areas to private companies such as Kodiak Transfer. Prior to 2006, the airport and leased areas were incorporated in BASE Kodiak’s

SWPPP and BASE Kodiak had responsibility for stormwater compliance. AKDOT now has independent permit coverage and BASE Kodiak is no longer directly responsible for activities on AKDOT leased property (including the sublet areas).

USCG BASE Kodiak Stormwater Pollution Prevention Plan

Chapter 2 Planning & Organization

2-1 October 2015

Chapter 2 Planning and Organization

2-1 Overview Stormwater runoff is part of the natural hydrologic cycle. However, human activities can alter natural drainage patterns and add pollutants to rainwater and snowmelt that run off the earth’s surface and enter streams, rivers, lakes, and coastal waters. DEC, through the NPDES permitting process, requires that industrial activities develop and implement a SWPPP.

The 2015 MSGP requires development and implementation of a Stormwater Pollution Prevention Plan

(SWPPP). The SWPPP must contain the following elements:

Identification of permittee;

Stormwater pollution prevention team;

Site description;

Summary of potential pollutant sources;

Description of control measures;

Schedules and procedures;

Signature requirements.

The five major steps/processes used to develop and maintain the BASE Kodiak SWPPP are:

Planning and organization

Assessment

Stormwater control measure (and/or Best Management Practices (BMPs)) identification

(selection and plan design)

Stormwater control measure implementation and training

Evaluation and monitoring

The stormwater pollution prevention process follows a plan-do-check-act process. The intent is to identify and evaluate potential pollutant sources, develop ways to minimize impacts through BMPs and training, implement those BMPs, and monitor/inspect to determine effectiveness. If the monitor/inspection aspect reveals a need for further actions, the process is repeated.

2-3 Site Description

BASE Kodiak is located on the northeast portion of Kodiak Island, Alaska, approximately 8 miles south of the city of Kodiak. The facility is the U.S. Coast Guard's largest shore facility, occupying approximately 23,000 contiguous acres, including much of the Buskin River valley and Womens Bay.

Between the various USCG operating and support commands, there are approximately 1,100 military and

1,400 military dependents. The BASE provides support for USCG facilities, aircraft, and vessels throughout Alaska.

Many of the buildings and structures at the facility date from World War II when the facility was constructed as a naval base. Kodiak was a major staging area for North Pacific operations during World

War II. A naval submarine base and air station was constructed at Womens Bay and an army outpost, Fort Greely, was established near the Buskin River in April 1941, remaining until decommissioned in

December 1944. Bunkers and gun emplacements were built at Chiniak, Long Island, and Fort

Abercrombie. After the war, Navy and Army activities were phased out. The USCG took over the facilities in 1972.

2-3.1 Mission and Activities at BASE Kodiak

The USCG is a military, multi-mission, maritime service within the Department of Homeland Security and one of the nation's five armed services. Its core roles are to protect the public, the environment, and

U.S. economic and security interests in any maritime region in which those interests may be at risk. This includes international waters and America's coasts, ports, and inland waterways.

The USCG provides unique benefits to the nation because of its distinctive blend of military, humanitarian, and civilian law-enforcement capabilities. To serve the public, the USCG has five fundamental roles:

Maritime Safety: Eliminate deaths, injuries, and property damage associated with maritime transportation, fishing, and recreational boating. The service is always ready to respond to calls for help at sea.

Maritime Security: Protect America's maritime borders from all intrusions by: (a) halting the flow of illegal drugs, aliens, and contraband into the United States through maritime routes; (b) preventing illegal fishing; and (c) suppressing violations of federal law in the maritime arena.

Maritime Mobility: Facilitate maritime commerce and eliminate interruptions and impediments to the efficient and economical movement of goods and people, while maximizing recreational access to and enjoyment of the water.

National Defense: Defend the nation as one of the five U.S. Armed Services. Enhance regional stability in support of the National Security Strategy, utilizing the Coast Guard’s unique and relevant maritime capabilities.

Protection of Natural Resources: Eliminate environmental damage and degradation of natural resources associated with maritime transportation, fishing, and recreational boating.

2-4 October 2015

BASE Kodiak is the only USCG facility that supports both cutters and aircraft. Personnel assigned to

BASE Kodiak play a key role in USCG operations in western Alaska. Along with providing services for visiting cutters from the Pacific area, the BASE Kodiak team provides administrative, logistical, and family support to 13 operational units on Kodiak. These units combine to make the Kodiak complex the largest operational base in the USCG.

Primary activities at BASE Kodiak relate to cutter (vessel) and aircraft support including maintenance, fueling, piers, security, taxiways, runways, roads, hangers, utilities, bulk fuel, administration support, waste management/treatment, equipment and vehicle storage, de/anti-icing, snow management, and communication. Secondary activities include housing, recreation, childcare, food service, vehicle maintenance, shopping, and vehicle fueling.

2-3.2 Impervious Surface Estimate

The whole of BASE Kodiak covers 23,000 acres, which includes about 8,200 acres of mostly undeveloped watershed or 35% of the total base land area. The main industrial core area is 214 acres, about 46% of which is impervious. Overall, assuming the non-industrial areas are 15% impervious and the watershed portion has no impervious area, the overall BASE Kodiak impervious area is about 10%.

2-3.3 Receiving Waters Stormwater from the core BASE Kodiak industrial area discharges into Womens Bay and St. Paul

Harbor. See Figure 3-4. Closed Navy and Coast Guard landfills indirectly discharge into the Buskin

River after flowing through Red Lake and Lake Louise respectively. See Figure 3-2. The west side of

Nyman Peninsula discharges stormwater into Womens Bay and the east side discharges into St. Paul

Harbor. See Figure 3-4.

2-3.4 Wetlands No significant drainage from industrial areas goes into wetlands. The base’s primary wetland in terms of source water and habitat quality is an approximate 380-acre area west of Buskin Lake. This wetland is in the designated upper BASE Kodiak watershed outside the core BASE Kodiak industrial area.

The Buskin River is bordered by riverine habitats and riparian wetlands. The mouth of the Buskin River is a marine and estuarine wetland.

Throughout the lower Buskin Watershed (downstream of the Buskin Lake), there are numerous isolated shrub bogs and emergent wetlands that vary significantly in size.

Detailed wetland information can be found in the document: Dames & Moore, Revised Final Wetland

Delineation Study, US Coast Guard Integrated Support Command, Kodiak, Alaska, May 14, 1999.

2-3.5 Water Quality Standards Water Quality Standards in the state of Alaska are contained in 18 ACC 70 (amended as of April 8, 2012). The primary applicable fresh water resources associated with BASE Kodiak are the Buskin River and Lake Louise. The primary applicable marine waters associated with BASE Kodiak are St Paul

Harbor and Womens Bay.

2-3.5.1 Water Quality Impairment Status The Clean Water Act (CWA) mandates that each state develop a program to monitor the quality of its surface waters. Based on the monitoring program, the state must regularly prepare a report categorizing water bodies with regard to water quality. In Alaska, the most recent report is Alaska’s Final

2-5 October 2015

2014 Integrated Water Quality Monitoring and Assessment Report, December 23, 2013. Water bodies are placed into one or five categories as follows:

Category 1: Water Quality Standards Attained for All Uses. Water bodies are placed in this category if there are data to support a determination that the water quality standards and all of the uses are attained.

Category 2: Water Quality Standards Attained for Designated Uses. Water bodies are placed in this category if some of the water quality standards for the designated uses are attained.

Category 3: Data or Information Insufficient. Water bodies are placed in Category 3 if data or information is insufficient to determine that the water quality standards for any of the designated uses are attained.

Category 4: Impaired Waterbody. Impaired but Total Maximum Daily Load (TMDL) not required.

Waters have been determined to be impaired but do not need a TMDL. Category 4 waters are divided into three sub-categories:

4a TMDL Completed

4b Other Pollution Control Requirements are Reasonably Expected to Result in Attainment of the Water Quality Standard in a Reasonable Period of Time

4c Impairment is not caused by a Pollutant. Water bodies are placed in this category if the impairment is not caused by a pollutant affecting water quality, e.g., degraded riparian habitat.

Category 5: Impaired Waterbodies on the Section 303(d) List. Water bodies are placed in Category 5 if the water quality standard(s) are not attained, i.e., the water body is impaired for one or more designated uses by a pollutant(s) and requires a TMDL or water body recovery plan to attain

Alaska’s water quality standards (18 AAC 70).

Table 2-4 lists the impairment category for surface water bodies on or adjacent to BASE Kodiak.

Building and LOWS

3-4 K.1 The Hazardous Waste Storage Building is located at the north end of the Nyman Peninsula, south of the Steam Plant. A RCRA Part B permit has been approved for this facility. All materials are stored in closed containers on pallets in secondary containment. The types of materials/waste include waste solvents, waste paints and paint-related material, spent batteries, and other hazardous wastes. The storage area has seven blind sumps and no drains. A component of the facility is the Liquid Oily Water Separator (LOWS) facility. The LOWS facility is a chemically-enhanced batch oil/water separation system, located at the former location of N-56. The system is designed to treat oily liquids received by and generated at BASE Kodiak consisting of oily water, oil/water emulsions, and used oils. The reclaimed oil is used for fuel at the steam plant. LOWS primarily processes bilge water prior to discharge into the sanitary sewer.

LF-1 Coast Guard Landfill 3-2 L.1 The Coast Guard Landfill, estimated at 10 acres, is located in the Buskin River drainage area one mile north of the Kodiak Airport. The

USCG operated this landfill from approximately 1972 until 1987. The landfill was used for domestic waste disposal. Metal scrap and concrete debris were disposed in the west side of the landfill. When the landfill was closed, a combination of leachate collection and runoff diversion was installed. Water collected in the leachate collection/runoff diversion system is ditched and then piped to the sanitary sewer at the BASE Kodiak wastewater treatment plant. During the summer of 2000, an impervious clay liner was installed that significantly reduced the amount of rainwater infiltrating into the landfill and subsequent inflow into the sanitary sewer.

LF-2 Navy Landfill 3-2 L.2 The Navy Landfill covers 15 acres located approximately one-quarter mile southwest of the Coast Guard Landfill. Waste was disposed here from the 1940s to the early 1970s. In 1992, leachate from the landfill was observed seeping into three depressions that may have flowed into a lake at the toe of the landfill referred to as “Red Lake,” due to its distinctive rust color. The three depressions were filled during installation of a fence around the landfill. The landfill was capped during the summer of 2000. The cap has reduced if not eliminated risk to groundwater in the area.

3-3 NA Stormwater discharges from these facilities are authorized by a separate NPDES permit (AK-003142-9), and therefore the stormwater discharges are not a component of this SWPPP. It is included for reference. This complex of aircraft fueling related facilities is located on the east side of Seafarer Drive near building 10. The complex includes two “day” tanks (N19 & N20), the fill stand (N22), and the pump house (N21). The day tanks are fed from the supply tanks N10 or N12 located on Nyman Peninsula to the southwest of this area.

The “day” tanks and the fill stand have secondary containment that can, via valve, be discharged either to the storm drain or to Hangar 1

Oil/Water Separator (OWS). Drainage from N21 also goes to the Hangar 1 OWS.

14 Hangar 1 3-3 S.1 Hangar 1 is located about 2,000 feet southwest of the end of runway 36, at the head of Womens Bay. This hangar is the center of maintenance activity for C-130 aircraft based at BASE Kodiak. Aircraft maintenance performed inside the building includes:

Engine rebuilding and repair (T-56 shop)

Structural repair (metal shop)

Propeller repair (prop shop)

Rebuilding wheels and hydraulic lines

Welding

Aircraft washing in Bay 4

Electrical repair

Painting - Paint Booth

Engine fuel (gas) path cleaning is performed outside the building on the paved apron over the refueling pad. In this operation, gas path cleaner is introduced through lines into the engine. The engine is started and the gasoline path cleaner sprays out the exhaust. Depending on the engine undergoing cleaning, the waste is either allowed to discharge into the sanitary sewer or collected and sent off-station for disposal.

Fueling pits are connected via underground lines to an oil/water separator at the northeast corner of Hangar 1. The oil/water separator discharges to Jewel Beach (outfall IA-3).

Outside the hangar, there is one fueling pit (No. 4) for helicopters located on the tarmac. However, because it is necessary to fuel several helicopters at a time, and the fueling pit can accommodate only one, the Coast Guard also uses a fueling truck. The truck is a potential source of fuel that could drip or spill and enter the stormwater system.

Types of chemicals used or stored include lubricants, solvents, small quantities of spray paints, thinners, strippers, other engine fluids, engine gasoline path cleaner, detergents, used fuels, used oils, and waste solvent.
