SUBCHAPTER AVISIBLE EMISSIONS AND PARTICULATE MATTER
DIVISION 2INCINERATION
RULE §111.121Single-, Dual-, and Multiple-Chamber Incinerators

No person shall cause, suffer, allow, or permit the burning of domestic, municipal, commercial, or industrial solid waste as defined in §101.1 of this title (relating to Definitions) in a single-, dual-, or multiple-chamber incinerator, unless the conditions listed in paragraphs (1) - (6) of this section are met. For purposes of this section, the term "commercial waste" shall be defined as waste material generated from retail and wholesale establishments. The requirements of this section do not apply to hazardous waste incinerators, or hospital and medical/infectious waste incinerators.

  (1) Particulate emissions shall not exceed 0.18 gram per dry standard cubic meter (g/dscm) or 0.08 grain per dry standard cubic foot (gr/dscf), front-half of sampling train only, when corrected for 7.0% oxygen (O2) in the stack gas according to the formula.

  (2) Hydrogen chloride (HCl) emissions greater than 1.8 kilograms (4 pounds) per hour require a control device with a minimum removal efficiency of 95%.

  (3) Carbon monoxide (CO) emissions shall not exceed 120 parts per million by volume dry basis, when corrected to 7.0% O 2 in the stack gas as specified in paragraph (1) of this section. CO and O2 shall be measured at the same location. Upon the approval of the executive director of the Texas Natural Resource Conservation Commission (TNRCC), a total hydrocarbon (THC) standard may be chosen as an alternative to the CO standard. In such cases, the emissions shall not exceed 20 parts per million, when corrected to 7.0% O 2 in the stack gas as specified in paragraph (1) of this section. THC and O2 shall be measured at the same location.

  (4) Oxygen content shall be maintained at greater than 4.0% by volume of the emissions of the incinerator, measured at the exit of the incinerator, or at an alternate location approved by the executive director or a designated representative of the TNRCC. Incinerators subject to the requirements of this section may operate at O2 concentrations less than 4.0% by volume if compliance with paragraph (3) of this section can be continuously demonstrated at a lower O2 concentration.

  (5) Visible emissions shall not exceed an opacity of 5.0% averaged over any six-minute period.

  (6) Incinerators burning not more than 100 pounds per hour of domestic, municipal, commercial, or industrial solid waste, based on the total weight of materials burned, shall be subject to an opacity limit of 5.0% averaged over a six-minute period, the requirements of §111.127(d) of this title (relating to Monitoring and Recordkeeping Requirements), and the operating requirements of §111.129(1) of this title (relating to Operating Requirements); but shall be otherwise exempt from the provisions of this section and §§111.125, 111.127, and 111.129 of this title (relating to Incineration).
