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 offsite 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.

DIRECTIONS: 

 All recipients must complete and return this survey by April 10, 2013.

 Please identify clearly any response(s) that you consider to be confidential business 

information (CBI). Any responses not so identified will be included in a publicly available

1. What emissions source types experience startup and shutdown events?

The 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 times.

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:

For each emission source type, can you comply with the emissions limitation and/or work practices in the regulation that apply 

during normal operation during startup and shutdown events? Please enter a separate response for each emissions point type

Please enter any other comments 

regarding startup or shutdown here:

6. How do you determine the HAP emissions during the event? 

7. How are control devices and work practices used to minmize emissions during 

the startup or shutdown event?

8. What compliance determination method(s) do you use during startup and 

shutdown events (e.g., monitor with CEMS)? 

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)

4. What marks the end of the startup or shutdown event?

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?

 If "source test" is used as basis for emissions estimate, please provide a copy of the 

source test.

5. What safety issues are connected with a startup or shutdown event?

2. How often do startup or shutdown events occur? 

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. What triggers the equipment to experience a startup or shutdown 

event (e.g. hot startup, startup after an emergency shutdown, re-start, 

control device startup)?

 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
