### ENCLOSURE 1 

# 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 pollut ants (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 requireme nts, 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 con trol 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 technolo gy (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
mor e 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 stand ards 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 Hazard ous 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 mai ntain 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 m anner 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.

1. What emissions source types experience startup and shutdown events? 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? Please enter a separate response for each emissions point type below:

9.a. Please describe how HAP emissions would be minimized.

9.b. How much would it cost to minimize HAP emissions in this manner? 9.c. How much would HAP emissions be reduced compared to an uncontrolled event? (If "emission factor" is used as basis for emissions estimate, please provide the emission factor and sources of the emission factor. 1

9. During startup and shutdown events, if you cannot comply with the emissions limitation and/or work practices in the regulation that apply during normal operation, what is the minimum emissions level that could be achieved?

3. What is the average and range of event duration? 1.d. How are emissions released to the atmosphere (e.g., through a pressure relief device)? 1.c. How does the startup or shutdown event compare to normal operations (e.g., differences in flowrate, temp., pressure, alternate fuels used, alternate control devices used, etc.)? 1.a. Under normal operating conditions, do these emissions sources operate continuously? 1.b.

2 See List of HAPs in separate worksheet for a table of CAS numbers and HAPs

3 MACT- allowable emissions are the maximum emission levels allowed while in compliance with the MACT standards

4 Emission point type choices include: fugitive, vertical, horizontal, goose neck, vertical with rain cap, or downward-facing vent

5 Fugitive Angle: Specifies the rotation of the source from north (in the clockwise direction). The location coordinates should reflect the southwest corner of the area source as shown in this graphic:

6 Location of stack or southwest corner of a fugitive emissions release point

7 For control measures, please include all control measures used for that emission point, including but not limited to:
