SECTION A. SITE IDENTIFIER
Applicant/permittee:
Site Name:
Facility ID (as issued by DEP):

SECTION B. IMPOUNDMENT PLAN

Attach a description of the impoundment plan, including specifications, designs, and cross sections. Describe the design of the impoundment, including the proposed volumetric capacity of each impoundment and schedule for construction and operation.

SECTION C. DESIGN REQUIREMENTS

1. Attach a slope stability analysis of the dike system that is proposed to support the impoundment.
2. Attach calculations indicating the freeboard is capable of preventing overtopping, including overtopping caused by the 24-hour precipitation event to be expected once in 25 years.
Freeboard: inches.
3. Will/does the dike have sufficient structural integrity to prevent failure? What are the minimum safety factors of the dike for dynamic and static loads?
Safety factor for:
a. static load:
b. dynamic load:
4. Describe how the impoundment is (will be) equipped so that the flow of residual waste into the impoundment can be shut off immediately.
5. Describe how the dikes and berms are (will be) kept free of burrowing animals and plants with root systems capable of displacing earthen materials upon which the structural integrity of the dikes or berms is dependent.
6. Demonstrate that the impoundment will be surrounded by structures sufficient to prevent surface run off from a 25year, 24hour precipitation event from entering the impoundment:

SECTION C. DESIGN REQUIREMENTS (continued)

7. Describe how odors and the dispersal of residual waste or waste constituents by wind and water erosion shall be prevented:
8. Inside slopes (not applicable to impoundments with concrete wall):
a. What are the inside slopes (%)?
b. Are the inside slopes designed and constructed with sufficient protective cover to prevent wind and water erosion, and to preserve the structural integrity of the dike? Describe how the inside slopes are designed and constructed:
9. Outside slopes and terraces:
a. What are the outside slopes (%)?
b. Describe how the outside slopes and terraces of the impoundment are designed, constructed, and operated:
c. How are the outside slopes and terraces of the dike protected from wind and water erosion to preserve the structural integrity of the dike?

SECTION D. WASTE SOLIDIFICATION PLAN

1. Attach a plan, including necessary drawings, designs, specifications, timetables, waste analyses, and narrative descriptions to solidify the waste. The plan shall include laboratory and field test results showing that the waste can be solidified as proposed.
2. Indicate the minimum bearing capacity of the waste in the impoundment after the solidification process:
tons/ft2.
