# INFORMATION COLLECTION REQUEST FOR Off

-Site Waste and Recovery Operations

This information collection request is being conducted by the Environmental Protection Agency’s (EPA) Office of Air and Radiation (OAR) to assist the EPA Administrator in developing emission standards for Off

- Site Waste and Recovery Operations under Clean Air Act (CAA) section 112. The survey is being sent under the authority of Section 114 of the CAA.

BACKGROUND:
Section 112 (d) of the Clean Air Act (CAA) calls for EPA to promulgate national technology

-based emission standards for hazardous air pollutants (NESHAP) for sources emitting one or more of the HAP listed in CAA section 112(b). For major sources, these technology

-based standards must reflect the maximum degree of emissions reductions of HAP achievable (after considering cost, energy requirements, and nonair quality health and environmental impacts). In addition, under CAA section 112(d)(6), EPA is required to review the technology

-based standards and revise them “as necessary (taking into account developments in practices, processes, and control technologies)” no less frequently than every 8 years. Furthermore, we are required by section 112(f) (2) of the Clean Air Act (CAA) to assess the risk remaining (residual risk) eight years after the promulgation of maximum achievable control technology (MACT) standards under section 112(d). If we find the residual risk fails to protect public health with an ample margin of safety or to prevent (taking into consideration various factors) adverse environmental effects, we are required to promulgate

more stringent standards.

The Off

- Site Waste and Recovery Operations maximum achievable control technology (MACT) standards were promulgated on July 1, 1996 (see 61 FR 34140). We are collecting specific detailed information to support development of standards as part of our review as described above. Please note this survey is for off

site waste and recovery operations only.
CAA section 114(a) states that the Administrator may require any person who owns or operates any emission source, who manufactures emission control equipment or process equipment, who the Administrator believes may have information necessary for the purposes set forth in section 114(a), or who is subject to any requirement of the CAA (other than certain provisions under Title II), to provide EPA with information for the following purposes:

1. Developing or assisting in the development of the following:

a. State implementation plans (§§ 110 and 111(d)); b. New Source Performance Standards (NSPS) (§ 111);

c. National Emissions Standards for Hazardous Air Pollutants (NESHAP) (§ 112); d. Solid waste combustion or other related solid waste regulations (§ 129); 2. Determining whether any person is in violation of any standards or requirements developed under the authorities cited above; or 3. Carrying out any provision under the CAA (except certain provisions under Title II).
The Administrator may require that those persons identified above do the following so the Administrator may have the information necessary for the items listed in #1

- 3:

 establish and maintain records;

 make reports;

###  install, use, and maintain monitoring equipment, and use audit procedures, or methods;

 sample emissions (in accordance with such procedures or methods, at such locations, at such intervals, during such periods, and in such manner as the Administrator shall prescribe);

 keep records on control equipment parameters, production variables or other indirect data when direct monitoring of emissions is impractical;

 submit compliance certifications in accordance with section 114(a)( 3); and

 provide such other information as the Administrator may reasonably require.

Containers T he United States Court of Appeals for the District of Columbia Circuit vacated portions of two provisions in the EPA’s CAA section 112 regulations governing the emissions of HAP during periods of startup, shutdown and malfunction (SSM). Sierra Club v. EPA, 551 F.3d 1019 (D.C. Cir. 2008). Specifically, the Court vacated the SSM exemption contained in 40 CFR 63.6(f)(1) and 40 CFR 63.6(h)(1), that are part of a regulation, commonly referred to as the “General Provisions Rule,” that the EPA promulgated under section 112 of the CAA. When incorporated into CAA section 112(d) regulations for specific source categories, these two, now vacated, provisions exempted sources from the requirement to comply with the otherwise applicable CAA section 112(d) emission standard during periods of SSM. To be consistent with the Court’s decision, facilities must comply with the applicable standards at all time s.

For each emission source type, do the annual emissions estimate in the Enclosure 2A "Emissions (TPY)" field include the annual emissions from startup and shutdown events that you added in the "STARTUP EMISSIONS (TPY)" and "SHUTDOWN EMISSIONS (TPY)" fields?
