Guidelines for Determining Closure Activities at Inactive Unlined Landfill Sites, July 2001

The facility can accept materials approved for use under the DEP’s Guidelines for Determining Closure Activities at Inactive Unlined Landfill Sites, July 2001, other than C&D Fines and Residuals. The Materials, from the DEP’s Policy, are as follows:

F. Types of Materials Used for Closure Activities
1. The types of materials the Department will consider for grading and shaping materials include, but are not limited to, the following:

a. clean soil;
b. street sweepings;
c. contaminated soil as defined by DEP Policy 97-001 ;
d. approved grading and shaping materials (C&D fines, coal ash, etc. and others as may be approved);
e. dewatered catch basin cleanings from separate storm sewers only (not from combined sanitary and storm sewers);
f. dewatered dredge spoils (see DEP Policy 94-007); and,
g. residuals from solid waste processing facilities or recycling operations including, but not limited to;

1. residuals from C&D processing facilities;
2. residuals from Materials Recycling Facilities (recycling facilities, composting facilities, etc.).

2. The type and/or source of all materials used as grading and shaping materials shall be approved by the Department prior to use at the landfill. Testing of materials (chemical, physical, etc.) may be required to determine whether they are suitable as grading and shaping material. Use of grading and shaping materials will be authorized under an ACO and the closure plan approval, or other appropriate approval issued by the Department. This Guideline is considered equivalent to a generic Beneficial Use Determination, pursuant to 310 CMR 19.060, which allows the use of these materials as Grading and Shaping Material. Therefore, a separate Beneficial Use Determination is not required for use of the materials when they are approved as described in this paragraph.

3. Unprocessed MSW, C&D or any other unprocessed wastes will not be considered suitable for use as grading and shaping material in the closure of inactive unlined landfills.
