Except as specifically provided elsewhere in these rules, no facility may compost solid waste without a permit as provided in rule 1200-01-07-.02(2). Composting facilities, subject to a full permit on the effective date of this rule, must submit a part I and part II permit application to describe how it will comply with this rule. The application must be filed within 180 days of the effective date of this rule and implemented upon approval. The Division will not charge an application fee, nor require public notice of the application for facilities which already have permit-by-rule for composting.
2. Compost produced from the solid waste classification criteria outside the State of Tennessee, which is used or sold for use within the state, shall comply with rule 1200-01-07-.11(4) subparagraphs (a) classification criteria; (b) labeling requirements; and (c) testing.

4. The following facilities or activities are not subject to the requirement to have a permit.
(i) Backyard composting and the resulting compost;
(ii) Normal farming operations. For the purpose of this rule, composting of only landscaping/land clearing waste, hereafter referred to as landscaping waste, or manure by persons on their own property for their own use on that property as part of agronomic or horticultural operations will be considered normal farming operations;
5. A composting facility processing up to 10,000 cubic yards per year of only landscaping waste and manure may receive a permit pursuant to rule 1200-01-07-.02(1)(c) Permits by Rule, for Solid Waste Processing.

(a) Classification Criteria
1. Type of waste processed
(i) Landscaping waste only
(ii) Landscaping waste and manure
(iii) Solid waste (may include sewage, sludge, and other solid waste)
2. Product maturity
(i) Mature compost is a highly stabilized compost material that has been exposed to prolonged periods of decomposition. It will not reheat upon standing to greater than 20° C above ambient temperature. The material should be brown to black in color. This level of maturity is indicated by a reduction of organic matter of greater than 60 percent.
(ii) Semi-mature compost is compost material that is at the mesophilic stage. It will reheat upon standing to greater than 20° C above ambient temperature. The material should be light to dark brown in color. This level of maturity is indicated by a reduction of organic matter of greater than 40 percent but less than or equal to 60 percent.
(iii) Fresh compost is compostable material that has been through the thermophilic stage and has undergone partial decomposition. The material will reheat upon standing to greater than 20° C above ambient temperature. It has beneficial use, but proper care is needed as further decomposition and stabilization will occur. This level of maturity is indicated by a reduction of organic matter of greater than 20 percent but less than or equal to 40 percent.
3. Compost shall be classified as either Type A Compost or Type B Compost according to its metal content characterization as shown in this part. Metal concentrations in finished compost shall not exceed the concentrations shown in Type B Compost below:

4. Foreign matter shall be expressed as a percent as provided at part 4 of subparagraph (c).
(b) Labeling Requirements.

Compost shall be labeled in accordance with the classification criteria of subparagraph (a) above. This label shall be prominently displayed on individually packaged material, or a written statement providing the classification criteria and certifying its accuracy will be deemed sufficient on all bulk sales. This label shall be of sufficient contrast to the packaging to be easily visible and shall be a bordered label with dimensions of three inches by five inches. The lettering shall be one quarter inch block characters.

(c) Testing
1. Compost shall be sampled and analyzed as follows:

2. The Department may decrease or increase the parameters to be analyzed for or the frequency of analysis based on monitoring data, changes in the waste stream or processing, or the potential presence of toxic substances. Sample collection, preservation, and analysis shall assure valid and representative results pursuant to a Department-approved quality assurance plan.
3. Composite samples shall consist of at least three individual samples of equal volume taken from separate areas along the side of the pile of the compost produced. Each sampling point shall be at a depth of two feet into the pile and four feet from the outside edge of the pile.
4. Foreign matter content shall be determined by passing a dried, weighed sample of the compost product through a one-quarter inch or six millimeter screen. EPA Method 160.3 shall be used to dry the sample. The material remaining on the screen shall be visually inspected, and the foreign matter that can be clearly identified shall be separated and weighed. The weight of the separated foreign matter divided by the weight of the total sample multiplied by 100 shall be the percent dry weight of the foreign matter content.
5. The organic matter reduction is determined by measuring the volatile solids content using EPA method 160.4.
(d) Reporting - Facility owner or operators shall record and maintain at the facility for three years the following information regarding their activities for each month of operation of the facility. Records shall be available for inspection by Department personnel during normal business hours and shall be sent to the Department upon request to include:
