(7) Ash from the combustion of municipal solid waste; and

(8) Sludge or septage as defined by RSA 485-A:2.

(d) Putrescible wastes not incorporated into an active composting process or amended with high carbon bulking agents within 2 hours of receipt shall:

(2) Not be stored at the facility longer than 7 days before being incorporated into an active composting process.

(e) Compostable feedstocks shall be combined into a homogenous mixture that will support aerobic composting conditions.

(f) During the active composting process, windrows, piles, or vessels shall be inspected, monitored, and actively managed to ensure that:

(1) Aerobic composting conditions are maintained; and

(2) The process complies with the general operating requirements in Env-Sw 1005.01.

(g) Temperature shall be monitored and recorded as follows:

(1) Temperature readings shall be recorded as specified in Env-Sw 605.03; and

(2) For each temperature monitoring event, temperature readings shall be taken and recorded as follows:

a. For a windrow or aerated static pile, in at least five evenly-spaced locations along the length of the windrow or pile;

b. For a round pile, in at least 2 locations on opposite sides of the pile; and

c. For an in-vessel system, in at least 2 evenly-spaced locations per vessel, compartment, bay, or equivalent.

(h) Prior to distribution and use, finished compost shall meet the quality requirements specified in Env-Sw 605.04, and the maturity requirements specified in Env-Sw 605.05.

(i) Testing to verify compliance with (h) above shall be conducted:

(1) At least once annually and when requested by the department pursuant to Env-Sw 2000; and

(2) On the basis of representative sampling.

(2) Date of individual windrow or pile construction and breakdown, or vessel filling and emptying;

(3) Composition of the windrow, pile, or vessel;

(4) Date and time of turning or aeration;

(5) Temperature monitoring records, including:

a. Temperature readings, including units;

b. Date and time of temperature readings;

c. Location and depth of temperature readings;

(6) Process monitoring observations, including, but not limited to:

a. Moisture content; and

b. Odor observations;

(7) Records of nuisance complaints made by abutters, or other parties, and corresponding response actions taken by the facility operators;

(8) Date on which composted material begins and finishes curing;

(9) Sampling and testing records, in accordance with Env-Sw 605.04 and Env-Sw 605.05, including;

a. Date, time, volume, method, and type of samples taken; and

b. Testing results;

(10) Quantities of finished compost produced on an annual basis;
