The plan shall identify specific actions that will be taken to address complaints if unacceptable odors occur beyond the property line of the operation;f. implementing a vector control plan that is appropriate for the size and type of the operation that will minimize the presence of vectors. The plan shall identify specific actions that will be taken to address complaints if unacceptable vectors occur beyond the property line of the operation;g. employing an appropriate number of properly trained personnel for the size and type of the operation;h. using equipment that is appropriate for the size and type of the operation; andi. developing a contingency plan that describes corrective actions to be taken for management of the organic materials and products in the event of equipment breakdowns, delivery of unacceptable material, spills, fires, extreme weather conditions or other events, including but not limited to the failure of the odor or vector control plan;3. ensure that the operation is located at least 250 feet from any existing water supply well in use at the time the operation commences;4. ensure that the type and quality of organic materials is sufficient for the operation and that the quality of the operation's products is sufficient for the products to be marketable;5. ensure that the organic material and products are not contaminated by toxic substances at levels which may pose a significant threat to public health, safety or the environment, including but not limited to implementing a toxics control plan that: a. will minimize entry of toxic materials into the operation;b. is appropriate for the organic materials to be managed at the operation; andc. ensures that the final products resulting from the operation do not pose a significant threat to public health, safety or the environment. Should toxics be detected in the final products at levels that pose a significant threat to public health, safety or the environment for any likely use of the product, the plan shall also include a contingency plan that identifies steps to be taken to reduce toxics in incoming organic materials, describes corrective actions to be taken for management of the organic materials and products, and identifies how any contaminated products are to be used or disposed;
6. ensure that the amount of residuals generated does not average more than 5% by weight of the materials received during any quarter;7. ensure that all solid and liquid materials produced as a result of the operation are managed in accordance with all other applicable regulations and approvals, including but not limited to, a beneficial use determination;8. not allow materials, in their as-received, in-process or processed condition, to be stored for more than one year from the date of their receipt at the operation. This time limit may be exceeded in the case of storage of a processed material pending accumulation of one full container load;9. maintain accurate records for at least three years to demonstrate compliance with 310 CMR 16.04 and submit a report to the Department annually by February 15th on a form provided by the Department that shall include, but not be limited to, the amounts and types of organic materials received and composted and the amount of residuals managed during the previous calendar year; and10. submit a compliance certification in accordance with 310 CMR 16.06(1).(b)Additional Requirements for a Composting Operation. The owner and operator of a composting operation shall comply with 310 CMR 16.04(3)(a) and shall: 1. ensure that no more than 25%, by volume, of the total compost mixture shall be a Group 2 Organic Material listed at 310 CMR 16.04(3)(b): Table 1. Example of Organic Materials or other organic materials with a carbon to nitrogen ratio of 30:1or less;2. ensure that adequate and appropriate bulking material (consisting of Group 1 organic materials listed at 310 CMR 16.04(3)(b): Table 1. Example of Organic Materials or other organic materials with a carbon to nitrogen ratio of greater than 30:1) is readily available on-site to mix with incoming Group 2 organic materials or other organic materials with a carbon to nitrogen ratio of 30:1 or less;3. ensure that all Group 2 organic material or other organic materials with a carbon to nitrogen ratio of 30:1 or less is mixed into the compost windrows or piles to such an extent that it is unrecognizable as a separate material as soon as possible but no later than the close of business each day, or transferred off-site by the close of business on the same day that it is received at the operation; and4. ensure timely and regular aeration of the compost to ensure proper aerobic, temperature, moisture and porosity conditions.
