RE: OSWRO Survey

Dr. Ms. Kissell:

On March Ii, 2013, Penny Lassiter, Group Leader Refining and Chemicals Group, USEPA

mailed a letter to John Scott Kuhn, Clean Harbors Environmental Services. That letter

requested information about emissions of hazardous air pollutants (HAP) and other related

information.

This is a response for Safety-Kleen Systems, Inc., a subsidiary of Clean Harbors located at 601

Riley Rd., East Chicago, IN 46312. Attached is a completed Enclosure 1, noting that the facilityis not an Off-Site Waste and Recovery Operations facility.

If you have any questions, you can contact me at 219-391-6127.

Respectfully,

A4u5

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 1 12(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 1 12(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 (MAC’T) 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 infbrmation 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 (NES[-IAP) ( 112); d. Solid waste combustion or other related solid waste regulations ( 1 29) 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 11).

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