The certification process must determine that the requirements in 8.1(A) (1) have been evaluated and incorporated in the CMP.(3) Agricultural Composting Operations must comply with the Department's Chapter 211 "Rules for the Disposal of Animal Carcasses", and "Best Management Practices for Animal Carcass Composting" (Attachment F) when composting offal or animal carcasses. C.Development of Recipes for Materials to be Composted(1) Specific blends of compostable materials must be developed by determining the moisture content, bulk density, pH, volatile solids, and carbon: nitrogen ratio of the materials to be composted. (2) The blend of materials must facilitate thermophilic microbial activity during the composting process.2.Sampling and Testing Ingredients ParametersA. Parameters to be used for sampling and testing ingredients for any new bulking materials used in the compost recipe: (6) Acidity or alkalinity (pH)B. Parameters to be used for testing ingredients for compost to be applied on the farm owner's fields: (7) Acidity or alkalinity (pH)C. Parameters to be used for compost products that may be distributed to the public, which must be used for making recommendations to purchasers for utilizing the compost(s). At least once annually, a representative sample of the compost must be sampled and analyzed for:(11) Maturity (Solvita or Dewar tests)D.Composting Time and Temperature Standard to be used for compost products that may be distributed to the public(1) Compost must attain 131 degrees F. for at least 3 consecutive days as measured at the piles core or three feet from the surface, whichever is less, for pathogen reduction for compost products that do not contain animal carcasses. (2) Compost that contains animal carcasses must be produced consistent with the operational requirements for compost systems described in the Department's Chapter 211 "Rules for the Disposal of Animal Carcasses".3.Requirements for Persons Writing Compost Management PlansA. CMPs may be developed or updated by the owner or operator of an Agricultural Composting Operation, a Maine certified nutrient management planning specialist, or other qualified individual as determined by the Commissioner.B. Training in a recognized CMP development program may be accepted as a means to becoming a qualified individual. 4.Record KeepingA. A record must be kept by the owner or operator of the Agricultural Composting Operation of all feedstocks that are produced on or brought onto the farm that are intended to be composted, which includes the source, type and volume of the material, for at least one year.B. A record must be kept by the owner or operator of the Agricultural Composting Operation of the volume of each compost product sold or removed from the site. The record shall be kept for at least one year.C. Testing results, as required under §8.2 shall be maintained by the composter for at least one year after the product has been distributed.D. Temperature charts for each windrow or pile shall be maintained by the composter for at least one year after the product has been distributed.E. Records shall be provided to the Department on request.5.Term of Certification for Compost Management PlansA. The CMP certification authorizes the named Agricultural Composting Operation to operate at the location designated in the CMP for a term of 5 years from the issue date under the conditions set forth in the CMP, with which the certification holder must comply.B. The CMP must be updated and re-certified by the Department every five years, or sooner, if there is any significant change in the operation that renders the existing CMP no longer relevant. Significant changes include, but are not limited to: (1) An increase or decrease in the volume of materials to be composted by 15% or more;(2) A change in the types of materials to be composted which would require an alteration of the ingredient-specific composting recipes; (3) A change in the basic type of composting system used, e.g., changing from a turned windrow system to an aerated static pile system;(4) A change in the location of the composting operation; or(5) Any other changes or aspects of the operation determined by the Department to be significant.C. CMPs held by Agricultural Composting Operations that were developed prior to January 1, 2012 will expire one year after the effective date of this Rule update unless re-certified in accordance with the provisions of these Rules.6.Site Inspections by the DepartmentA. The owner or operator of an active Agricultural Composting Operation shall, upon reasonable notice, submit to inspections by the Department during normal business hours to ensure that the CMP holder's operation is in compliance with the provisions of the CMP.B. The Department must conduct a site inspection of the proposed composting site prior to the certification of any CMP. 7.Revocation of Compost Management Plan CertificationA.Basis of certification revocation. The Commissioner may revoke certification of a CMP if the owner or operator of the Agricultural Composting Operation fails to comply with any of the requirements of these Rules.B.Notice. When the Commissioner decides to revoke a certification, he/she shall provide the certificate holder a written notice of the certification revocation immediately following the decision. The notice shall be sent by certified mail, return receipt requested, and must include:(1) The name and address of the owner/operator whose certification is being revoked;(2) The effective date of certification revocation;(3) A statement or list of reason(s) why certification is being revoked; and (4) Notice of the right to request a hearing in accordance with §8.7(C) of these Rules.C.Hearing on Compost Management Plan Certification Revocation(1) The Commissioner shall hold a hearing on a CMP certification revocation when: (a) A person receiving a notice of revocation requests a hearing in writing to the Commissioner; and(b) The request for a hearing is made no later than 30 days after receipt of the revocation notice required under §8.7(B) of these Rules.(2) The Commissioner shall notify the person requesting a hearing in writing of the date, time and location of the hearing.(3) The hearing shall be held in accordance with the requirements of 5 M.R.S.
