GRINDSTONE WASTEWATER LAGOON OPERATION CONTRACT

SCOPE OF WORK

C.1 Scope of Contract The individual performing the work must possess a current Class IV (or higher) Wastewater License.

Description of Work:

The intent of this contract is for the contractor to perform as-needed discharging of the Grindstone Campground wastewater lagoon in strict accordance with the parameters outlined in the Commonwealth of Virginia’s Department of Environmental Quality VPDES Permit Number VA0022993, Grindstone Recreation Area Sewage Treatment Plant, Smyth County (included). Work will be conducted on an as-needed basis, with both the Forest Service COR and the contractor acting as monitors of the wastewater lagoon’s water level. When the water level approaches the top of the lagoon liner, discharge will be needed. The contractor must always ensure that the above-mentioned VPDES Permit is adhered to and that flow, pH, BODs, Suspended Solids, Ammonia Nitrogen, Dissolved Oxygen, and Total Residual Chlorine are monitored and recorded per VA DEQ requirements. The Forest Service will provide chlorination and de-chlorination tablets and anti-algae bacterial additive. Contractor will be required to furnish all necessary transportation and labor, as well as testing supplies and equipment.

Testing parameters, record keeping, and reporting must be in compliance with VPDES Permit Number VA0022993 and are clearly outlined therein. The contractor will find all necessary information for successful lagoon discharge in the Permit.

The past operation of this facility indicates that discharging the lagoon requires as many as 25 consecutive days of operator presence, dependent upon water level and precipitation. The contracted operator must be present at the Plant on discharge days to monitor flow. These 25 days of discharge may be repeated as many as 4-5 times a calendar year.

Contractor Responsibility: Contractor to furnish its own insurance.

C.3 Location and Description of Grindstone Recreation Area Sewage Treatment Plant Grindstone Campground physical address: 1946 Laurel Valley Road, Troutdale, VA, 24354.

From Interstate 81, take exit 45 at Marion onto Virginia State Highway 16 South. Follow VA Hwy 16 south for approximately 17 miles and then turn right onto State Route 603. The Campground will be on the left and the Wastewater Lagoon site will be on the right just past the campground.

Sewage Treatment Plant Description The Grindstone Recreation Area Sewage Treatment Plant is a two-stage, open cell, wastewater lagoon that is discharged into Big Laurel Creek following treatment at a weir chamber below the lower lagoon. The lower polishing lagoon has failed and is inoperable, leaving only the upper lagoon operational. This lack of system integrity makes in-parameter discharge especially complex. The campground’s bathhouses, which supply the Plant with wastewater, are shutdown indefinitely because of the failure of the lower lagoon. Now, only rainwater and runoff infiltrate the upper lagoon, yet it must still be discharged within the parameters of the Permit. Experienced and knowledgeable Forest Service personnel will be available to the contractor to assist in discharging.
