Environmental Protection Agency April 1, 2008 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is hereby giving notice that the State of Iowa is revising its approved Public Water Supply Supervision Program under the Iowa Department of Natural Resources. The EPA has determined that these revisions are no less stringent than the corresponding Federal regulations. Therefore, the EPA intends to approve these program revisions.

EPA is proposing to amend the national perchloroethylene air emission standards for dry cleaning facilities promulgated on July 27, 2006 (71 FR 42724), under the authority of section 112 of the Clean Air Act. These amendments to the national perchloroethylene air emission standards for dry cleaning facilities would correct applicability cross references that were not correctly amended between the most recent proposed and final rule revisions, and would clarify that condenser performance monitoring may be done by either of two prescribed methods (pressure or temperature), regardless of whether an installed pressure gauge is present. Without these amendments, new area sources could erroneously be required to perform monitoring that was proposed for only major sources, and installed condenser performance gauge readings could be required of sources when a prescribed temperature method is just as valid for compliance purposes. In the ``Rules and Regulations'' section of this Federal Register, we are issuing these corrections as a direct final rule with this parallel proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.
