Solid Waste Systems - Emissions Design Criteria

The following information is our standard solid/municipal waste design criteria. We will guaranty to meet or exceed these specifications.

TNRCC Chapter 106 - Permit By Rule, and Chapter 111, Division 2- Incineration, Considerations, Standards and Specifications for Dual-Chamber Incinerators

HTT proposes the installation of an incinerator for the destruction 0-4 (Typical solid waste as well as pathological). The facility will consist of a dual combustion chamber incinerator that will fire only natural gas fuel. In order for the proposed project to qualify for a TNRCC Chapter 106, Permit by Rule authorization, and to meet TNRCC Chapter 111, Incineration Standards, and the following incinerator design specifications must be met:

The incinerator shall be equipped with an afterburner automatically controlled to operate with a minimum temperature of 1,400 degrees Fahrenheit (°F) and a minimum gas retention time of 0.5 seconds (Section 106.491).

Stacks shall have unobstructed vertical discharge when the incinerator is operated (properly installed and maintained spark arrestors are not considered obstructions) (Section 106.491). The stack height shall be at least 10 feet above the peak of the highest building within 150 feet of the facility (Section 106.491).

Fuel for the incinerator shall be limited to sweet natural gas, LPG or #2 fuel oil with less than 0.5% sulfur by weight (Section 106.491). The manufacturer shall provide written recommended operating instructions, which shall be posted at the incinerator, and the unit shall be operated in accordance with these instructions (Section 106.491).

The following TNRCC Chapter 111, Sections 111.121 and 111.127 incinerator limits must be met:

a) Opacity of emissions from the incinerator shall not exceed 5% averaged over a six-minute period;

b) A continuous monitor of incinerator temperature must be installed;

c) Drawings showing the dimensions of the afterburner firebox must be provided such that the firebox volume can be readily calculated from the drawings;

d) A stack test showing the exhaust flow rate and temperature must be conducted so that the minimum gas retention time (residence time) can be certified prior to TNRCC approval of the request for authorization for the facility.

For facilities qualified under the PBR 106.491, the Chapter 111 requirements to install carbon monoxide (CO) and oxygen (O2) monitors in the incinerator are not required but there is a limit of 120 parts per million (ppm) CO that is specified in the rule (Section 111.127) and the rule also requires that oxygen content must 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 TNRCC). Note: If continuous compliance with the 120 ppm CO limit can be continuously demonstrated then the incinerator may operate at O2 concentrations less than 4.0% by volume.

TNRCC Chapter 111, Section 111.121 incinerator limits include a particulate matter (PM) emission limitation from incinerators of 0.08 grain PM per dry standard cubic foot of exhaust flow (gr/dscf) when corrected for 7.0% oxygen in the stack gas (not including condensables). The rule provides a formula for use in calculating the corrected concentration of PM. Oxygen in the stack gas must be measured using the Orsat method for O2 analysis of dry flue gas [see 40 Code of Federal Regulations, Part 60, Appendix A (Method 3)].
