A complete list of all chemicals, pesticides, fuels and other potentially toxic or
hazardous materials to be manufactured, used or stored on the premises in
quantities greater than those associated with normal household use, accompanied
by a description of measures proposed to protect all storage containers/facilities
9-2
from vandalism, corrosion and leakage and to provide for the control of spills. 2. A description of potentially toxic or hazardous wastes to be generated, indicating
storage and disposal methods. 3. Evidence of approval by the DEP of any industrial waste treatment or disposal
system or any wastewater treatment system with a capacity of 15,000 gallons per
day or more. 4. Projections of downgradient concentrations of nitrogen and other relevant
chemicals at property boundaries and other locations deemed pertinent by the
SPGA. Projections shall be based upon appropriate ground water models and the
following information/ standards:
a. Nitrogen loading calculations. - Wastewater per person: 5 lbs. of nitrogen per year
- Persons per dwelling: 3
- Lawn fertilizers: 2 lbs. of nitrogen per 1,000 square feet of lawn
area per year
- Road runoff: 0.19 lbs. of nitrogen per curb mile per day
- Background nitrogen concentration: actual field measurements
b. Groundwater flow and impacts to drinking water and supply wells. - Identify probably impacted water supply well(s) by constructing
flow lines on the Easton Water Table Map (IEP, 1986)
downgradient of the proposed site
- Use 15 inches per year for sand and gravel and 7 inches per year
for till for aril recharge rates
- Determine the value for hydraulic conductivity from the closest
downgradient public water supply well in the Easton Aquifer
Protection Plan (IEP, 1986)
- Determine the saturated thickness of the site as shown on the
Saturated Thickness Map (IEP, 1986) supplemented with on-site
borings. 5.
