Part 63 Subpart DDDDD National Emission Standards for Hazardous Air Pollutants for Major Sources: for Industrial, Commercial, and Institutional Boilers

Incorporated by Reference (IBR) Format

Changes made in the proposed amendments of 12/23/11 to Subpart DDDDD:

1. Removed dioxin/furan standards / must conduct tune-ups as a work practice for dioxins/furans (Table 3 #3).

2. Re-established standards for Total Selected Metals, with compliance demonstrated through fuel analysis (option to standards for filterable particulate matter).

3. Changed the parameter monitoring from 12-hour block averages to 30-day rolling averages.

4. Added back in the option to use CO CEMS for compliance with the CO standards (O2 CEMS in final of 3/21/11) with the option to install an oxygen analyzer or oxygen trim system (40 CFR 63.7525(a))

5. Removed the requirement to conduct fuel specification analysis for hydrogen sulfide for other gas 1 gaseous fuels.

6. New subcategories added for heavy and light liquid fuels.

7. Added a 5-year tune-up (reduced from biennial) requirement for boilers/process heaters less than 5 MMBtu/hr designed to burn natural gas, refinery gas, other gas 1 fuels, gas 2 fuels, and light liquid fuels.

8. Added or replaced PM CEMS with PM CPMS, with the output in milliamps, PM concentration, or other raw data signal value.

9. Added option to install Hg CEMS (and when available HCl) to demonstrate compliance with the Hg standard.

Under Part 63, Subpart DDDDD, per 40 CFR 63.7490:

The process heater is a new or reconstructed source if construction or reconstruction commenced after 6/4/10.

The process heater is an existing source if construction or reconstruction commenced on or before 6/4/10.

Part II - FACILITY SPECIFIC TERMS AND CONDITIONS

A.State and Federally Enforceable Permit-To-Install Facility Specific Terms and Conditions

0. The permittee shall comply with the applicable provisions of the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Industrial, Commercial, and Institutional Boilers and Process Heaters, as promulgated by the United States Environmental Protection Agency under 40 CFR Part 63, Subpart DDDDD. The final rules found in 40 CFR Part 63, Subpart DDDDD establish national emission standards for hazardous air pollutants (NESHAP), operational limits, work practice standards, and compliance requirements for industrial, commercial, and institutional boilers and process heaters located at a major source of hazardous air pollutants (HAP). The permittee shall comply with the requirements and limits of this NESHAP for the facilitys new (commenced construction after 6/4/10) process heaters by the compliance date identified in 40 CFR 63.7495(a) or upon startup; and the facilitys existing process heaters shall be in compliance with 40 CFR Part 63, Subpart DDDDD no later than the compliance date identified in 40 CFR 63.7495(b).

[40 CFR 63.6(b)(2)], [40 CFR 63.7485], [40 CFR 63.7490], and [40 CFR 63.7495]

The terms in this permit identify the requirements of the National Emissions Standards for Hazardous Air Pollutants (NESHAP) contained in 40 CFR Part 63, Subpart DDDDD and are meant to help the permittee maintain compliance with this NESHAP. The requirements of this Subpart apply to the facility process heaters according to their applicable subcategory, as defined in 40 CFR 63.7575.
