ENVIRONMENTAL REPORT for j 1

CONSTRUCTION of DECOMMISSIONING SUPPORT FACILITIES SAXTON NUCLEAR EXPERIMENTAL CORPORATION l

i INTRODUCTION The purpose of this environmental report is to discuss the environmental

~

impact of the construction of the Saxton Nuclear Experimental Corporation (SNEC) decommissioning support facilitiet (DSF). This report is intended to  !

satisfy Item No. 5. of the USNRC Request for Additional Information, dated March 25, 1996. It is understood that Item No. 5. specifically requests SNEC 4

. to address the environmental impact of DSF construction only. Item No. 5.

states that the environmental impact related to the use and operation of the DSF after construction should be included in the Environmental Report of the SNEC Decommissioning Plan.

1 BAGK6ROUND ,

The DSF will consist of three interconnected pre-engineered metal buildings which will be directly connected to the SNEC facility Containment Vessel. The buildings will be constructed at grade on concrete slabs and will be serviced with' electricity. There is no water service, wastewater drainage (sanitary or industrial), or air emission sources other than normal building heating and

- ventilation exhaust included in the design of the three buildings. Stormwater from' roof drains and building area runoff will be directed to the existing i

yard drainage system or to a French drain system to be constructed as part of the DSF construction project. Although the DSF buildings will be constructed  :

to meet industry standards for permanent structures, the DSF buildings are classified as temporary structures and are planned to be dismantled upon 8

completion of SNEC facility decommissioning activities. The DSF building

. construction and associated SNEC facility site work will be accomplished in accordance with a GPU Nuclear engineering specification (reference no.1).

CONSTRUCTION ACTIVITIES - ENVIRONNENTAL INPACT Buildina Permits and Certificates of Occupancy The SNEC facility is located in Liberty Township, Bedford County. The building contractor will be responsible for securing the required Building Permits and Certificates of Occupancy from Liberty Township and the

Pennsylvania Department of Labor and Industry (PAD 0LI). The building design and construction will meet the applicable local and state building codes for the type of construction, building location, designated building uses and anticipated personnel occupancy. PAD 0LI requirements will be invoked for the DSF project because of the potential for the buildings to be occupied by four or more individuals during the workday. The DSF buildings are classified as

. temporary structures and are planned to be dismantled upon completion of SNEC facility decommissioning activities. Building demolition would be accomplished in accordance with applicable codes and standards.

PAGE 2. OF 4 -

SAXTON DSF CONSTRUCTION ENVIRONMENTAL REPORT Floodplain Manaaement 4

The DSF buildings will be constructed in an area at the Saxton site which is above the 100 year floodplain. The three buildings will be located at site elevations between 812 feet and 813 feet (reference no.1). In the 1972 Saxton Decommissioning Plan and Safety Analysis Report (reference no. 2), the maximum observed flood elevation at the Saxton site was reported at 809.5 feet. This maximum observed flood elevation was recorded in March 1936 and corresponded to a river flow of about 80,000 cubic feet per second (cfs). As stated in the 1972 Saxton Decommissioning Plan, the Army Corps of Engineers assigned a 225 year flood frequency to the 80,000 cfs flow at the Saxton site (reference no. 2). In March 1996, the U.S. Geological Survey (USGS) provided data to SNEC that confirmed the observed high flows for the Raystown Branch of the Juniata River at Saxton, PA. occurred in March 1936 (reference no. 3).

In an effort to update the 100 year floodplain information for the Saxton site

the USGS, the Federal Emergency Management Agency (FEMA) and the Army Corps of Engineers were contacted in March 1996. The closest USGS river flow gage for the Raystown Branch of the Juniata River is located about 1.5 miles upstream from the Saxton site and is of limited use for direct determination of the 100 year flood frequency river elevation at the Saxton site. Both FEMA and the Army Corps of Engineers indicated that later Saxton site data were not available beyond what was referenced in the 1972 Saxton Decommissioning Plan.

Based upon the available floodplain information, SNEC concludes that the DSF buildings will be constructed above the 100 year floodplain as the 225 year flood elevation is below the planned DSF building elevation. Therefore, the building construction is not subject to PADEP Bureau of Dams and Waterways Management or Army Corps of Engineers permitting.

J Given the short duration of the construction period (approximately three months) and the predicted flood frequency at the Saxton site, the likelihood of a flood occurring during the construction period is extremely unlikely.

The Raystown dam and reservoir operated by the Army Corps of Engineers located downstream of the SNEC facility site provide additional flood control for the facility. However, should a flood event occur during construction activities, sufficient notice of imminent flooding would be available for the building contractor to implement steps to minimize impact on the public and the environment. For example, loose construction materials as well as equipment containing hazardous substances could be relocated to high ground.

Stormwater Manaaement Stormwater runoff from the construction area will be directed to the existing site stormwater collection and drainage system. Site stormwater is retained onsite and there is no stormwater point source discharge to local surface waters. Site stormwater intermittently ponds onsite and percolates into local soils and groundwater. The USEPA National Pollutant Discharge Elimination System (NPDES) permit program covers stormwater discharges from certain types of construction activities (reference no. 4). However, the USEPA NPDES permit program regulations as administered by the PADEP exempt construction activities that result in the disturbance of less than five acres and are not part of a larger common plan of development or sale (reference no. 4).

~

PAGE 3 0F 4 SAXTON DSF CONSTRUCTION ENVIRONMENTAL REPORT The SNEC facility site covers approximately 1.148 acres (reference no. 2) and the combined area covered by the DSF building footprint and the associated site road work and grading will cover about one acre (reference no. 1). Since the affected area is less than five acres the USEPA stormwater permitting program related to construction activities is not applicable. During earthmoving activities associated with DSF building construction soil erosion from stormwater runoff will be controlled in accordance with applicable PADEP and Soil Conservation District reqeirements. The following section of this  ;

report discusses the soil erosion control plan for the SNEC facility site. '

Soil Erosion and Sedimentation Control The SNEC facility site has a relatively flat topography ar.d is not prone to accelerated stormwater runoff and soil erosion. SNEC fadlity site soil erosion and sedimentation will be minimized during DSF construction activities by implementation of the SNEC Soil Erosion and Sedimentation Control Plan (reference no. 5). This plan is based upon the PADEP Erosion Control regulations (reference no. 6). The plan requires the use of temporary control measures such as fabric filter fencing, mulching and straw bales during earthmoving activities and permanent site stabilization upon completion of earthmoving activities. The PADEP does not require an erosion control permit for DSF construction activities because less than 25 acres of land will be disturbed. ,

1 Air Quality - Fucitive Emissions l The PADEP requires persons involved in construction activities to take reasonable actions to prevent particulate matter from becoming airborne 1 (reference no. 7). Reasonable actions include the use of water to minimize airborne dust from the construction area and the prompt removal of earth or other materials from paved roads in the construction area. Because there will be a limited amount of earthmoving activities and transporting of dirt and other construction materials associated with DSF construction, fugitive emissions are anticipated to be minimal. The building contractor will be required to implement dust control methods to prevent visible airborne dust from crossing the GPU System owned property boundaries which surround the SNEC facility site. Onsite dust control will be implemented by the building contractor if needed to assure a suitable work environment for contractor and other onsite SNEC personnel.

Waste Manaaement The building construction activities will generate typical construction wastes such as wood, metals, bricks, block, and roofing materials. These wastes are classified as construction / demolition waste under the PADEP Municipal Waste Management regulations (reference no. 8). Construction / demolition wastes generated from the DSF project will be managed, transported and disposed of in accordance with the PADEP's municipal waste regulations. Empty hazardous ,

material containers generated from construction altivities will also be i managed and disposed of as municipal waste. l

j -

i PAGE 4 0F 4 SAXT0N DSF CONSTRUCTION ENVIRONNENTAL REPORT 4

The generation of other wastes that are not classified as construction /

demolition waste will be minimal. The building contractor will be required to

. minimize the generation of wastes such as paints, solvents, and cleaning liquids that may be used on the project. For example, open containers that contain usable product will be retained by the contractor for use on other

_ projects if applicable. SNEC recognizes that some liquid wastes or other '

solid wastes may be generated which cannot be properly managed as municipal 3

waste. In this case the waste will be managed and disposed of in accordance with the PADEP Residual Waste Maragement regulations (reference no. 9) or the PADEP Hazardous Waste Manaor .o regulations (reference no.10) as appropriate. Also, inadve tent spills of hazardous substances will be cleaned-up and the impacted area will be remediated as necessary. Spill '

i residues will be properly disposed of and regulatory agencies will be notified

] if threshold spill rcperting quantities are exceeded.

j Other Environmental Features - Historical and Endanaered Species

! The SNEC facility site is located on property which has been associated with j industrial activity since the 1920's. The SNEC facility site is located adjacent to property owned by the Pennsylvania Electric Company, a subsidiary

] of General Public Utilities Corporation, which was the site of the Saxton j Steam Electric Generating Station (SSEGS). The coal-fired SSEGS was operated from 1923 to 1974 and was demolished during the period 1975 to 1977. The area of the SNEC facility site where the DSF buildings will be constructed was

! - previously occupied by the SNEC facility Control and Auxiliary Building. The Control and Auxiliary Building was a support facility for the SNEC power plant which was constructed from 1960 to 1962. The Control and Auxiliary Building was demolished with other SNEC facilities in 1992.

l There are no known historical or archaeological areas of interest located at

, the SNEC facility site or the adjacent Pennsylvania Electric Company property

(reference no. 11). There have been no historical or archaeological areas

! identified during earth disturbances associated with construction and

demolition of the SNEC facility and the SSEGS. Also, there are no known endangered or threatened plant or animal species on the SNEC facility site or the adjacent Pennsylvania Electric Company property (reference no.11).

! ENVIRONNENTAL INPACT - SUNNARY SNEC does not anticipate any significant environmental impact related to the DSF construction project. The building contractor and SNEC personnel will comply with the applicable environmental regulations and good work practices during construction activities. The building contractor will be responsible for securing all required regulatory permits and approvals for the '

construction project. Building construction and occupancy permits will be secured from both Liberty Township and PAD 0LI. Because of the relatively small size of the project and the determination that the building construction is outside of the 100 year floodplain, there are no other environmental permits identified for this project.
