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.

All composting and mulching facilities are required to follow the general requirements in 30 TAC § 332.4 and the air quality requirements in § 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.
