SWMU 14 - Old Pesticide Disposal Area CERCLA and Petroleum Site

Land Use Restrictions
Outdoor recreational and commercial and industrial land uses for the CERCLA Downtown Area sites are allowable under the OU A ROD. Examples of recreational land uses include hiking, bird watching, hunting, nature watching or any other short-term, non-intrusive activity on the land. Examples of commercial and industrial uses include manufacturing, industrial research and development, utilities, commercial warehouse operations, retail gas stations, auto service stations, equipment repair and service stations, professional offices, financial institutions, publicly owned office buildings, retail business where the principal activity is the sale of food or merchandise, personal service establishments (health clubs, barber/beauty salons, mortuaries, photographic studios, etc.), churches providing worship services (excluding daycare services), and motels/hotels (excluding those that allow residences). The planned land use at the Downtown Area CERCLA sites (except landfills) is consistent with these land use restrictions.

Soil Excavation Restrictions
Excavation Notifications are required for all the Downtown Area CERCLA sites as an IC. The excavation notifications will be required for all proposed excavations below 2 feet at each of the ICs sites. The notifications will be evaluated to determine whether a proposed project at an IC site is consistent with the land use restrictions. The notifications are an additional tool for the Navy to receive timely information (in the absence of local zoning requirements) to monitor land use restrictions. The primary purpose of the IC Excavation Notification is to apprise the Navy of any changes in land use. Information regarding the depth to contamination present is available in the information repository on the second floor of Bob Reeves High School. In the event of an emergency excavation for utility repairs, the requester shall notify the Navy within three working days after the emergency repair has been completed to provide the name, location, depth, and duration of the excavation.

Groundwater Restrictions
Domestic use of groundwater in the Downtown Area is restricted because of the potential presence of petroleum compounds and other chemicals in the groundwater. Domestic groundwater use is defined as that used by households or transients for human and animal consumption, cooking, bathing, showering, gardening, irrigation, or use on consumable food products, watering animals and any other domestic use. The excavation notification program at individual sites provides one barrier to drilling; enforcement of the prohibition will also occur through periodic visual inspections. The visual inspections will focus on unauthorized wells in the restricted area. Groundwater use restrictions are included in the equitable servitude.

Inspections and Reporting
The ICs identified in this plan will be inspected and reported on an annual basis, or as necessary. Annual site inspection reports will present the results of inspections. The annual reporting requirements will be included in CERCLA 5-year reviews.

Land Use Restrictions
Commercial and industrial land uses and continuing residential land uses where housing exists in the Downtown Area are permitted in accordance with the Interim Conveyance document. Residential housing is allowed in existing housing units located at Amulet Housing, Arctic Acres Housing and SWMU 62. Future residential housing construction will be evaluated for impacts to ongoing petroleum cleanup activities.

Soil Excavation Restrictions
Soil excavation notifications are required for all the Downtown Area Petroleum sites with ICs. The excavation notifications will be required for each proposed excavation below 2 feet. The notifications will be evaluated to determine whether a proposed project at an IC site is consistent with the land use restrictions. The notifications are an additional tool for the Navy to receive timely information (in the absence of local zoning requirements) to monitor land use restrictions.

Other Engineering Controls
Other engineering controls include landfill caps (CERCLA sites), free-product recovery wells (SAERA sites), and free-product recovery trenches (SAERA sites).
