Mr. Richard Wright APR 1 3 *|g98 

Senior Engineer 

Ashland Chemical Company 

5200 Blazer Memorial Parkway 

Dublin, Ohio 43017 - . 

Dear Mr. Wright: 

This letter is to request a visit by the U.S. Environmental Protection Agency (EPA) 

and its representatives to the Ashland facility in Houston, Texas on April 22, 1998. Visitors 

will include Mr. Stephen Shedd ofthe EPA, and Mr. Greg LaFlam and Mr. Bernd Haneke of 

Pacific Environmental Services, Inc. (PES). Mr. Haneke of PES discussed this visit with you 

in a telephone conversation on April 7, 1998. We anticipate arriving at the facility at 12:30 

p.m. 

As you are aware, the EPA is developing national emission standards for hazardous air 

pollutants (NESHAP) for organic liquids distribution (non-gasoline) facilities. The main 

emission sources of interest are as follows: 1) storage tanks; 2) loading and unloading 

operations; 3) equipment leaks; 4) waste and wastewater treatment and disposal operations; 

and 5) mixing and blending operations. To assist in the development of this NESHAP, the 

EPA is collecting information on emissions of hazardous air pollutants (HAP) from these 

emission sources and on the types of emission controls used on each of the sources. 

During the visit to your facility, we wish to: 1) discuss the facility's mixing and 

blending operations; 2) discuss the facility's emission control operations; 3) observe the 

storage tanks, wastewater systems, organic liquid transfer operations, and any associated 

emission control and emission monitoring equipment. Enclosure 1 identifies the type of 

information that we would like to obtain during our visit, and also contains a listing of the 

materials considered to be HAP by the EPA. Feel free to provide any additional information 

that you believe is critical to our understanding of these processes, their HAP emissions, or 

the emission controls. Collection and organization of the information identified in Enclosure 1 

prior to our visit will greatly facilitate information exchange during the visit. 

The authority for the EPA's information gathering is included in section 114 of the 

Clean Air Act (42 U.S.C. 7414). Enclosure 2 contains a summary of this authority. If you 

believe that disclosure of the information we request would reveal a trade secret, you should 

clearly identify such information as discussed in the enclosure. Any information subsequently 

determined to constitute a trade secret will be protected under 18 U.S.C 1905. If no claim of 
P.3 

confidentiality accompanies the information when it is received by the EPA, it may be made 

available to the public by the EPA without further notice (40 CFR Part 2.203, September 1, 

1976). Since section 114(c) of the Clean Air Act exempts emission data from claims of 

confidentiality, the emission data you provide may be made available to the public. A 

clarification of what the EPA considers to be emission data is contained in Enclosure 3. 

As noted in Enclosure 4, the EPA has designated PES as an authorized representative 

of the Agency. Therefore, PES has the rights discussed above and in Enclosure 4. As an 

authorized representative ofthe EPA, PES is subject to the provisions of 42 U.S.C. 7414(c) 

respecting confidentiality of methods or processes entitled to protection as trade secrets. The 

PES contract with the EPA is No. 68-D60013. 

Enclosure 5 summarizes the EPA policies and procedures for handling privileged 

information and describes the EPA contractor commitments and procedures for use of 

confidential materials. It is the EPA's policy that compliance by an authorized representative 

with the requirements detailed in Enclosure 5 provides sufficient protection of the rights of 

those submitting privileged information. 

The following policies concerning liability should also be of interest to you: 

1. If a Federal employee is injured in the course of his employment, he has 

compensation coverage from the Government under the Federal Employees Compensation Act 

(5 U.S.C 8108 et seq.); and 

2. If, due to the employee's negligence, property damage or personal injury to third 

parties occurs, the Federal Tort Claim Act (28 U.S.C. 1346) provides a means of fixing any 

liability upon the Federal Government. 

The Office of General Counsel has informed the Agency that a firm may not condition 

the EPA's "right of entry" upon consent to a waiver of liability and has instructed employees 

not to sign such waivers. If you have any questions regarding this refusal, please contact the 

EPA's General and Information Law Division at (202) 260-0020. 

2. 
P.4 

Thank you for your cooperation. If you have any questions, please contact Mr. Steve 

Shedd of my staff at (919) 541-5397, or Mr. Greg LaFlam of PES at (919) 941-0333. 

Sincerely,

Enclosure 1 

SUMMARY OF ORGANIC LIQUIDS DISTRIBUTION INFORMATION OF INTEREST 

To assist in the collection of information during the requested site visit, a summary of 

the information to be collected is provided below. At this time, this information pertains 

specifically to each of the emission sources of interest: 1) storage tanks; 2) loading and 

unloading operations; 3) equipment leaks; and 4) waste and wastewater treatment and disposal 

activities. As we learn more during the visit, additional HAP sources could be added to our 

scope.

Product throughputs (e.g., bbl/year of each organic liquid), and process 

technical description, with simplified schematics and a plot plan of the entire 

facility. 

Types/concentrations of hazardous air pollutants (HAP) in tanks/wastewater 

streams (or annualized mass emission rates) prior to emission control device. 

Types of emission reduction measures or control devices associated with each of 

the emission sources, if any. 

Control device efficiency or concentration of HAP in air streams (or annualized 

mass emission rates) subsequent to the emission control device(s), if applicable. 

Capital and operating costs associated with the emission control device(s), if 

applicable. 

Operating and maintenance experience associated with the emission control 

device(s) (i.e., identify key operating parameters for efficient control, 

parameters that indicate poor control, or problems associated with a specific 

emission source/control device combination). 

Types of emission monitoring devices used to monitor emissions or control 

device performance, as applicable. 

Rationale for selecting any emission control devices currently installed on the 

operations.
