NESHAP for Cyanide Chemicals Manufacturing (40 CFR 60, subpart YY) (Final Rule)

NOTE: RIN changed between proposed and final rule. This final rule ICR was published with RIN # 2060-AU67 [86 FR 66096], while - due to ROCIS system limitations -- this entry is using the RIN from the proposed rule ICR, 2060-AU64 [86 FR 3906]. This supporting statement addresses information collection activities that will be imposed by amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the cyanide chemicals manufacturing source category in the Generic Maximum Achievable Control Technology standards, 40 CFR part 63, subpart YY, referred to as the cyanide chemicals manufacturing maximum achievable control technology (MACT) standards. The current cyanide chemicals manufacturing MACT standards were promulgated on July 12, 2002 (67 FR 46257). As part of the residual risk and technology reviews (RTR) for the NESHAP, the Environmental Protection Agency (EPA) is finalizing amendments to (1) clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction; (2) add requirements for electronic reporting of performance test results; and (3) add wastewater requirements (including the incorporation of test methods for wastewater stream free cyanide concentration measurements) for new and existing affected sources. This information collection request documents the monitoring (including applicability testing/calculations), recordkeeping and reporting requirements and burden imposed by these amendments.
