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

Startup and Shutdown Events

If no for any of the above, please explain:

The operating units run continuously and 

emissions are vented to the facility 

hazardous waste incinerator. When the 

incinerator shuts down, emissions are 

directed to a backup carbon absorption 

system. As such there is no startup and 

shutdown of the emission source.

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

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)?

PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR 

SOURCE CATEGORIES (CONTINUED) 

Subpart PP—National Emission Standards for Containers

§ 63.923 Standards—Container Level 2 controls.

(a) This section applies to owners and operators subject to this subpart and required to control air 

emissions from containers using Container Level 2 controls.

(b) A container using Container Level 2 controls is one of the following:

(1) A container that meets the applicable U.S. Department of Transportation (DOT) regulations on 

packaging hazardous materials for transportation as specified in paragraph (f) of this section.

(2) A container that has been demonstrated to operate with no detectable organic emissions as 

defined in § 63.921 of this subpart.

(3) A container that has been demonstrated within the preceding 12 months to be vapor-tight by 

using Method 27 in appendix A of 40 CFR part 60 in accordance with the procedure specified in 

§ 63.925(b) of this subpart.

(c) Transfer of regulated-material in to or out of a container using Container Level 2 controls shall 

be conducted in such a manner as to minimize exposure of the regulated-material to the atmosphere, 

to the extent practical, considering the physical properties of the regulated-material and good 

engineering and safety practices for handling flammable, ignitable, explosive, or other hazardous 

materials. Examples of container loading procedures that meet the requirements of this paragraph 

include using any one of the following: a submerged-fill pipe or other submerged-fill method to load 

liquids into the container; a vapor-balancing system or a vapor-recovery system to collect and control 

the vapors displaced from the container during filling operations; or a fitted opening in the top of a 

container through which the regulated-material is filled, with subsequent purging of the transfer line 

before removing it from the container opening.

(d) Whenever a regulated-material is in a container using Container Level 2 controls, the owner or 

operator shall install all covers and closure devices for the container, and secure and maintain each 

closure device in the closed position except as follows:

(1) Opening of a closure device or cover is allowed for the purpose of adding material to the 

container as follows:

(i) In the case when the container is filled to the intended final level in one continuous operation, 

the owner or operator shall promptly secure the closure devices in the closed position and install the 

covers, as applicable to the container, upon conclusion of the filling operation.

eCFR — Code of Federal Regulations Page 1 of 3

http://www.ecfr.gov/cgi-bin/text-idx?c=ecfr&SID=907066c5e04ce3c78ec41a430b5b0c3e&rgn=div8&vie... 5/1/2013
(ii) In the case when discrete quantities or batches of material intermittently are added to the 

container over a period of time, the owner or operator shall promptly secure the closure devices in the 

closed position and install covers, as applicable to the container, upon either the container being filled 

to the intended final level, the completion of a batch loading after which no additional material will be 

added to the container within 15 minutes, the person performing the loading operation leaves the 

immediate vicinity of the container, or the shutdown of the process generating the material being 

added to the container, whichever condition occurs first.

(2) Opening of a closure device or cover is allowed for the purpose of removing material from the 

container as follows:

(i) For the purpose of meeting the requirements of this section, an empty container as defined in 

§ 63.921 of this subpart may be open to the atmosphere at any time (e.g., covers and closure devices 

are not required to be secured in the closed position on an empty container).

(ii) In the case when discrete quantities or batches of material are removed from the container but 

the container does not meet the conditions to be an empty container as defined in § 63.921 of this 

subpart, the owner or operator shall promptly secure the closure devices in the closed position and 

install covers, as applicable to the container, upon the completion of a batch removal after which no 

additional material will be removed from the container within 15 minutes or the person performing the 

unloading operation leaves the immediate vicinity of the container, whichever condition occurs first.

(3) Opening of a closure device or cover is allowed when access inside the container is needed to 

perform routine activities other than transfer of regulated-material. Examples of such activities include 

those times when a worker needs to open a port to measure the depth of or sample the material in the 

container, or when a worker needs to open a manhole hatch to access equipment inside the container. 

Following completion of the activity, the owner or operator shall promptly secure the closure device in 

the closed position or reinstall the cover, as applicable to the container.

(4) Opening of a spring-loaded pressure-vacuum relief valve, conservation vent, or similar type of 

pressure relief device which vents to the atmosphere is allowed during normal operations for the 

purpose of maintaining the container internal pressure in accordance with the container design 

specifications. The device shall be designed to operate with no detectable organic emissions when the 

device is secured in the closed position. The settings at which the device opens shall be established 

such that the device remains in the closed position whenever the container internal pressure is within 

the internal pressure operating range determined by the owner or operator based on container 

manufacturer recommendations, applicable regulations, fire protection and prevention codes, standard 

engineering codes and practices, or other requirements for the safe handling of flammable, 

combustible, explosive, reactive, or hazardous materials. Examples of normal operating conditions 

that may require these devices to open are during those times when the container internal pressure 

exceeds the internal pressure operating range for the container as a result of loading operations or 

diurnal ambient temperature fluctuations.

(5) Opening of a safety device, as defined in § 63.921 of this subpart, is allowed at any time 

conditions require it to do so to avoid an unsafe condition.

(e) The owner or operator shall inspect containers using Container Level 2 controls in accordance 

with the procedures specified in § 63.926(a) of this subpart.

(f) For the purpose of compliance with paragraph (b)(1) of this section, containers shall be used 

that meet the applicable U.S. DOT regulations on packaging hazardous materials for transportation as 

follows:

(1) The container meets the applicable requirements specified in 49 CFR part 178—Specifications 

for Packagings or 49 CFR part 179—Specifications for Tank Cars.

Title 40: Protection of Environment 

PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR 

SOURCE CATEGORIES (CONTINUED) 

Subpart DD—National Emission Standards for Hazardous Air Pollutants from Off-Site Waste and 

Recovery Operations

§ 63.689 Standards: Transfer systems.

(a) The provisions of this section apply to the control of air emissions from transfer systems for 

which § 63.683(b)(1)(i) of this subpart references the use of this section for such air emission control.

(b) For each transfer system that is subject to this section and is an individual drain system, the 

owner or operator shall control air emissions in accordance with the standards specified in 40 CFR 

part 63, subpart RR—National Emission Standards for Individual Drain Systems.

(c) For each transfer system that is subject to this section but is not an individual drain system, the 

owner or operator shall control air emissions by using one of the transfer systems specified in 

paragraphs (c)(1) through (c)(3) of this section.

(1) A transfer system that uses covers in accordance with the requirements specified in paragraph 

(d) of this section.

(2) A transfer system that consists of continuous hard-piping. All joints or seams between the pipe 

sections shall be permanently or semi-permanently sealed (e.g., a welded joint between two sections 

of metal pipe or a bolted and gasketed flange).

(3) A transfer system that is enclosed and vented through a closed-vent system to a control 

device in accordance with the requirements specified in paragraphs (c)(3)(i) and (c)(3)(ii) of this 

section.

(i) The transfer system is designed and operated such that an internal pressure in the vapor 

headspace in the enclosure is maintained at a level less than atmospheric pressure when the control 

device is operating, and

(ii) The closed-vent system and control device are designed and operated in accordance with the 

requirements of § 63.693 of this subpart.

(d) Owners and operators controlling air emissions from a transfer system using covers in 

accordance with the provisions of paragraph (c)(1) of this section shall meet the requirements 

specified in paragraphs (d)(1) through (d)(6) of this section.

(1) The cover and its closure devices shall be designed to form a continuous barrier over the 

entire surface area of the off-site material as it is conveyed by the transfer system except for the 

openings at the inlet and outlet to the transfer system through which the off-site material passes. The 

eCFR — Code of Federal Regulations Page 1 of 2

inlet and outlet openings used for passage of the off-site material through the transfer system shall be 

the minimum size required for practical operation of the transfer system.

(2) The cover shall be installed in a manner such that there are no visible cracks, holes, gaps, or 

other open spaces between cover section joints or between the interface of the cover edge and its 

mounting.

(3) Except for the inlet and outlet openings to the transfer system through which the off-site 

material passes, each opening in the cover shall be equipped with a closure device designed to 

operate such that when the closure device is secured in the closed position there are no visible cracks, 

holes, gaps, or other open spaces in the closure device or between the perimeter of the opening and 

the closure device.

(4) The cover and its closure devices shall be made of suitable materials that will minimize 

exposure of the off-site material to the atmosphere, to the extent practical, and will maintain the 

integrity of the equipment throughout its intended service life. Factors to be considered when selecting 

the materials for and designing the cover and closure devices shall include: organic vapor 

permeability; the effects of any contact with the material or its vapors conveyed in the transfer system; 

the effects of outdoor exposure to wind, moisture, and sunlight; and the operating practices used for 

the transfer system on which the cover is installed.

(5) Whenever an off-site material is in the transfer system, the cover shall be installed with each 

closure device secured in the closed position except as specified in paragraph (d)(5)(i) or (d)(5)(ii) of 

this section.

(i) Opening of closure devices or removal of the cover is allowed to provide access to the transfer 

system for performing routine inspection, maintenance, repair, or other activities needed for normal 

operations. Examples of such activities include those times when a worker needs to open a hatch or 

remove the cover to repair conveyance equipment mounted under the cover or to clear a blockage of 

material inside the system. Following completion of the activity, the owner or operator shall promptly 

secure the closure device in the closed position or reinstall the cover, as applicable.

(ii) Opening of a safety device, as defined in § 63.681 of this subpart, is allowed at any time 

conditions require it to do so to avoid an unsafe condition.

(6) The owner or operator shall inspect the air emission control equipment in accordance with the 

requirements specified in § 63.695 of this subpart.

Water / Oil emission factors apply to water streams in oil service with a water content greater than 50%, from 

the point of origin to the point where the water content reaches 99%. For water streams with a water content 

greater then 99%, the emissino rate is considered negligible.

The "other" equipment type was derived from compressors, diaphrams, drains, dump arms, hatches, 

instruments, meters, pressure relief valves, polished rods, relief valves, and vents. This "other" equipment type 

should be applied for any equipment type other then connectors, flanges, open-ended lines, pumps, or valves.
