South Coast Air Quality Management District, Form 500-H (2014.07)
With the exception of emission units that are municipally-owned backup utility power units as described by 40 CFR Part 64, Section 64.2(b)(2)
1
, the CAM rule is applicable to each emission unit
(existing and new construction) at a Title V facility that meets ALL of the following criteria
2
:
1. The emission unit is subject to an emission limitation or standard
3
(often found in permit conditions);
2. The emission unit uses a control device to achieve compliance with the emission limitation or standard; and,
3. The emission unit has a potential to emit (PTE)
4
, either pre-control or post-control depending on the type of Title V application
5
, that exceeds or is equivalent to any of Title V major
source thresholds shown in the following table:

For Individual Emission Units at a Title V Facility
(tons per year)
1 The facility must attach the documentation required by 40 CFR Part 64, Section 64.2 (b)(2) to demonstrate that the backup utility power unit only operates during periods of peak demand or emergency situations; and has actual
emissions, averaged over the last three calendar years of operation, less than 50% of the major source emission thresholds.
2 Additional information about the CAM rule can be found on EPA’s website at http://www.epa.gov/ttnemc01/cam.html.
3 Only emission limitations and standards from an “applicable requirement” for emission units with control devices are subject to the CAM rule. Applicable requirements are federally-enforceable requirements that are rules adopted by
AQMD or the State that are approved by EPA into the State Implementation Plan (SIP) (i.e. “SIP-approved rules”). Refer to Form 500-C1 for the latest versions of SIP-approved and non-SIP approved rules.
For emissions units with control devices that are subject to following federally enforceable requirements, the CAM rule does NOT apply: 1) NSPS (40 CFR Part 60); 2) NESHAP (40 CFR Parts 61 and 63); 3) Title VI of the Federal Clean
Air Act (CAA) for Stratospheric Ozone Protection; 4) Title IV of the CAA and SCAQMD Regulation XXXI for Acid Rain facilities; 5) SCAQMD Regulation XX – RECLAIM; 6) Any emission cap that is federally enforceable, quantifiable,
and meets the requirements in 40 CFR Part 70, Section 70.4 (b)(12); and 6) Emission limitation or standards for which a continuous compliance determination method is required.
4 To calculate the pre
-control device and post-control device PTE for emission units at the facility, refer to the Title V Technical Guidance Document Version 4 .0, Appendix A (pages A-12 through A-23). The calculations are used to
determine the CAM applicability according to 40 CFR Part 64, Section 64.5 of the CAM rule.
5 For initial Title V or significant permit revision applications submitted after April 20, 1998, use the post
-control device PTE emissions to determine CAM applicability. For Title V permit renewal applications (submittals will begin in 2002),
the CAM applicability will be based on the pre
-control device PTE.
6 The following table is based on Rule 3001 (Amended November 14, 1997) and Rule 3008 (Amended March 16, 2001). Please be advised that the threshold values are subject to change based on rule amendments.
