MoreThe EPA in its Thursday, Oct. 21, 2010, Federal Register announced how it would like to address the residual risk and technology reviews conducted for two national emission standards for hazardous air pollutants (NESHAPs). Piggybacking on its October 2008 proposal, the agency is proposing six NESHAPs for 16 source categories, 12 of which are the subject of residual risk and technology reviews in this package.
The six NESHAPs and associated categories are as follows:
The six NESHAPs and associated categories are as follows:
| Chromium Electroplating | Chromium Anodizing Tanks |
| Decorative Chromium Electroplating | |
| Hard Chromium Electroplating | |
| Group I polymers and resins production | Butyl Rubber |
| Epichlorohydrin Elastomers | |
| Ethylene Propylene Rubber | |
| Hypalon | |
| Neoprene | |
| Nitrile Butadiene Rubber | |
| Polybutadiene Rubber | |
| Polysulfide Rubber | |
| Styrene Butadiene Rubber | |
| Latex | |
| Marine vessel loading operations | " " |
| Pharmaceuticals production | " " |
| Printing and publishing industry | " " |
| Steel pickling--HCl process facilities and hydrochloric acid regeneration plants. | " " |
The agency's proposal would modify the existing emissions standards for eight source categories in three of the six NESHAP to address certain emission sources not currently regulated under these standards. It also proposes for all six NESHAPs to address provisions related to emissions during periods of startup, shutdown and malfunction. Finally, this action proposes changes to two of the six NESHAPs to correct editorial errors, make clarifications, or address issues with implementation or determining compliance.
For the technology review for the chromium electroplating and anodizing source categories, the agency is proposing to amend the rules to prohibit the addition of PFOS-based WAFS to the electroplating or anodizing tanks. For these source categories, the agency is also proposing to require several housekeeping requirements to minimize emissions of chromium-laden fugitive dust from chromium electroplating operations, and for owners and operators to incorporate these housekeeping procedures in the facility operation and maintenance plan.
For MTVLO, the agency is proposing to lower the existing threshold for control of emissions from gasoline loading from 10 million bbl/yr to 1 million bbl/yr.
For the Group I polymers and resins, pharmaceuticals production, and printing and publishing industry MACT standards, which were addressed in the Oct. 10, 2008 proposal, the agency has reaffirmed its previous determinations that there have been no developments in practices, processes or control technologies. Thus, the agency is continuing to propose that it is not necessary to revise the existing MACT requirements based on its CAA section 112(d)(6) review.
For the steel pickling--HCl process facilities and hydrochloric acid regeneration plants source category, the agency also determined that there have been no developments to require new MACT standards.
Comments must be received by Dec. 6, 2010, but it's recommend (by the agency) that they arrive on or before Nov. 22, 2010. A public hearing will be held on Nov. 5, 2010.
