The Rhode Island Department of Environmental Management (RIDEM) finalized amendments to several Air Pollution Control Regulations (APCR). All of the final regulations will be effective January 09, 2017. The amendments are summarized below:
- Rhode Island Air Pollution Control General Definitions Regulation
The definition of "volatile organic compound" (VOC) is updated to be consistent with the current, federal definition.
- APCR No. 8 – Sulfur Content of Fuels
The amendment adds a definition for "alternative fuels" and lowers the allowable sulfur content for alternative fuels to be the same as residual fuel oils.
- APCR No. 19 – Control of Volatile Organic Compounds from Surface Coating Operations
Regulatory language is added to clarify that the emission limitations in the regulation do not apply if the source is also subject to the requirements in APCR No. 44 "Control of Volatile Organic Compounds from Adhesives and Sealants". Additionally, the registration requirements in this regulation are revised to be consistent with the requirements in APCR No. 14 "Record Keeping and Reporting".
- APCR No. 27 – Control of Nitrogen Oxide Emissions
- The frequency of compliance testing is reduced from annually to once every five years.
- The frequency of tune-ups for industrial-commercial-institutional boilers is reduced from annually to biennially.
- The tune-up procedure for boilers specified in 40 Code of Federal Regulation (CFR) 63, Subpart JJJJJJ and 40 CFR 63, Subpart DDDDD are allowed as an acceptable substitute for the procedure specified in Appendix A of this regulation.
- The method for determining compliance with the emission limits is revised to allow that compliance be demonstrated based upon the average results of three-one hour test runs to be consistent with federal requirements. The previous requirement was demonstrating compliance with each individual test run.
- APCR No. 35 – Control of Volatile Organic Compounds and Volatile Hazardous Air Pollutants from Wood Products
The regulation has been amended to revise the applicability threshold with respect to Hazardous Air Pollutants (HAPs). Previously, this regulation applied to any wood products facility that has the potential to emit 25 tons per year (tpy) or more of VOC from wood products manufacturing operations or is located at a major source of HAP. However, the regulation has been amended such that a facility will have be a major source of HAP specifically from wood products manufacturing operations to be subject to this regulation.
- APCR No. 36 – Control of Emissions from Organic Solvent Cleaning
- The small cold solvent cleaning machines that have internal volume equal to or less than one liter are now exempt from all the requirements of this regulation except for recordkeeping requirements.
- An alternative means of compliance is added for spray gun cleaning operations.
- The performance standards for when an air pollution control system is used as an alternative to low vapor pressure solvents are clarified.
