USGS Tunison Laboratory of Aquatic Science 3075 Gracie Rd., Cortland NY 13045 Demolition of Three (3) Residential Houses

1.0 Introduction and Background

Introduction: USGS, Great Lakes Science Center’s, Tunison Laboratory of Aquatic Science in Cortland, NY needs to have three (3) residential houses and three (3) accompanying garages, demolished. The houses and garages to be demolished are located adjacent to the Tunison lab’s 3075 Gracie Rd., Cortland NY property.

Background: The USGS Tunison Laboratory of Aquatic Science has three (3) residential wood framed houses used in the past to house hatchery staff trainees. Each house is approximately 2000 square feet (sf) and has a 1-stall garage and utilities including septic, wells and oil or gas heating systems. All houses were constructed prior to 1956 and likely contain lead paint and asbestos construction materials. The houses have not been occupied for at least 15 years and are in poor condition.

2.0 Scope

The three (3) residences adjacent to the Tunison lab will have their houses (3) and garages (3) demolished. All sidewalks, gardens, or yard fixtures associated with the 3 residences will be removed and disposed of according to local and state regulations.

An asbestos survey done in 2017 on the house and garage at residence Q2 (see attached documents) found friable ACM in joint compound on walls and ceilings and in heat duct fabric coverings in the house, and non-friable ACM in wall board glue in the house and in window glaze in the garage. Bids for demolition of all 3 houses should be prepared, assuming similar results will be found in residences Q1 and Q50.

Prior to demolition, USGS will have asbestos investigations prepared for the 2 houses and 2 garages at residences Q1 and Q50 so that asbestos containing materials can be removed and disposed of by the contractor properly following all local and state regulations. Considering the age of all 3 houses, all painted surfaces should be considered to have at least a base layer of lead paint and should be handled and disposed of appropriately. Contractors are responsible for acquiring all necessary permits for the project.

Before demolition begins all underground septic and utilities will be located, and the demolition plan will take those into account. Septic system infrastructure (tanks and piping) will be removed and disposed of according to local and state regulations. Onsite wells shall be removed and filled in. Fuel oil and propane tanks will be removed and disposed of according to local and state regulations. Any appliances (e.g., refrigerators, stoves, furnaces, hot water heaters) remaining in the residences will be removed and disposed of according to local and state regulations. Demolition material such as stone, concrete, or masonry rubble can be buried on site provided it complies with local and state laws. All other demolition materials will be hauled off site and disposed of according to local and state regulations. All areas affected by the demolition, other than existing gravel driveways, will be returned to a safe and level grade consistent with the immediate surrounding area, and will be seeded with grass.
