The Municipal Solid Waste (MSW) Permits Section has determined that MSW composting facilities may use analytical data prepared by a laboratory certified under the U.S. Composting Council Seal of Testing Assurance (STA) Program, using the Test Methods for the Examination of Composting and Compost (TMECC) protocols, to demonstrate compliance with end-product standards specified in 30 TAC Chapter 332. Compost end-product testing, including testing for heavy metals using EPA test methods may be performed by laboratories that certify compliance with STA program rules in lieu of accreditation by the TCEQ.

Financial Assurance Requirements for Composting and Mulching Facilities

If you store combustible material outdoors or your composting or mulching operation poses a significant risk to public health and safety, you are required to establish financial assurance in accordance with 30 TAC ß 328.5(c)ñ(e) for notification-tier facilities (unless excluded by 30 TAC ß 328.5(a)), registration-tier facilities, and certain exempt facilities, or in accordance with 30 TAC ß 332.47(9) for permitted facilities. The following documents provide additional information:

* Guidelines for Complying with Financial Assurance Requirements for Recycling, Composting, and Mulching Facilities (in PDF)
* Financial Assurance for Recycling, Composting, and Mulching Facilities - Summary of Adopted Rules (in PDF)

Information for all Composting and Mulching Facilities

The composting rules address composting, mulching and land application, and the beneficial reuse of nonhazardous organic materials. It is anticipated that the majority of composted materials will be diverted from the municipal waste stream; however, the rules also address agricultural materials, sludge, and other organic materials diverted from the industrial waste stream.

* Composting rules (30 TAC Chapter 332)
* Requirements for Nonhazardous Recycling and Composting Facilities (RG-410)
* Table summarizing applicability of rules affecting recycling activities and facilities (in PDF)
* Composting refund

All composting and mulching facilities are required to follow the general requirements in 30 TAC ß 332.4 and the air quality requirements in ß 332.8, which include compliance with all applicable state and federal laws. All activities must be conducted in a manner that prevents the discharge of material to or pollution of surface water or groundwater, the creation of a nuisance, or the endangerment of the public health and welfare, or the environment.

* In accordance with 30 TAC ß 332.8, qualifying composting and mulching facilities may pursue an air quality standard permit instead of a site-specific air quality permit.
* The discharge of wastewater and certain types of storm water into or adjacent to water in the state must be authorized by a water quality permit. In particular, a water quality permit is required for wastewater discharges from livestock manure composting operations.
