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.
