Martin, Governor William W. Cobey, Jr., Secretary March 31, 1989 Mr. M. W. Holcomb Senior Environmental Specialist Phillips Pipe Line Company 3 B10 Adams Bulding Bartlesville, OK 74004 SUBJECT: Draft Permit Comments NPDES Permit No. NC0032875 Phillips Pipe Line Company Selma Terminal Subbasin 030402 Johnston County R. Paul Wilms Director Per your request, the Division has reviewed your comments submitted to me by letter dated February 27, 1989, concerning a draft copy of the subject NPDES permit. Our response to these comments is as follows: 1. Permittee Designation: Phillips Pipe Line Company will be designated as the permittee. 2. Napthalene, Toxicity and Organics: These requirements should remain as set forth in the permit. They are based on current Divisional procedures for oil termi- nals and tank farms, and they are being consistently applied to all facilities of this type throughout the State. Napthalene is present in diesel fuel which is stored in the terminal. The whole effluent toxicity testing is necessary to evaluate the potential toxic impact of the discharge. Note that the require- ment is for acute toxicity testing for episodic events and that there is no chronic target. Regarding the comment about Part III, Condition H in the permit, this condition should read: "Within 60 days of the first dis- charge event, the permittee shall also submit the results of the following analyses. These analyses shall be performed on a rep- resentative sample of the stormwater effluent discharge, taken after any treatment (required one time only): P.O. Box 27687, Raleigh, North Carolina 27611-7687 Telephone 919-733-7015 An Equal Opportunity Affirmative Action Employer Mr. M. W. Holcomb March 31, 1989 Page Two 1) EPA Method 625 -Acid and Base/Neutral Extractable Organics and; 2) EPA Method 624-Purgeable Organics." 3. Phenols: This facility discharges approximately two miles upstream from surface waters classified "WSIII-NSW" which denotes a source of water supply for drinking, culinary, or food processing pur- poses. This classification protects the Town of Smithfield's water supply. Therefore, under North Carolina Administrative Code Title 15 2B. 0203, current Divisional procedure requires a 0.01 lb/day phenols effluent limitation to all oil terminals discharging into Mill Creek and its unnamed tributaries. At the water supply intake a phenols concentration of 1.0 ug/1 or less must be maintained at low flow conditions; the 0.01 lb/day phe- nols limit meets this criterion considering all other oil termi- nals discharging into the Mill Creek watershed. 4. Settleable Solids and Turbidity: Stormwater run-off is expected to contain solids and to be tur- bid by nature. The limitations contained in the permit for these two effluent parameters are based on North Carolina water quality standards. They are both applied to all oil terminals and tank farms by current Divisional procedure. Therefore, they should remain in the permit. However, the Division would not object to a 30 mg/1 TSS limit if Phillips Pipe Line Co. would accept it in lieu of the settleable solids limitation. 5. BOD5 and MBAS: According to our Raleigh Regional Office, a field investigation indicated that trucks are washed in the terminal, and the pro- cess wastewater is disposed of through the permitted outfalls. Therefore, based on a Division's study of wastewater character- istics, BOD5 and MBAS monitoring is appropriate to determine the extent of the impact of the truckwashing operation which is very unclear at this point. The Division would not object a permit condition indicating that no car wash or other process waste- water should be disposed of through the permitted outfalls in lieu of the monitoring requirements for BOD5 and MBAS. In this case, the Raleigh Regional Office will enforce compliance with this permit condition or any illegal discharges of process wastewater. Mr. M. W. Holcomb March 31, 1989 Page Three You may request all monitoring frequencies be revised after twelve months of data. At that time, any monitoring frequency may be reduced to 1/month should the data for a given parameter indicate that the concen- tration of such parameter is consistently well below the permit limita- tion. Please notify Mr. Arthur Mouberry, of the Permit and Engineering Unit, by April 14, 1989 should you accept the proposed TSS limitation and/or the permit condition regarding the process wastewater discharge. If you have any questions concerning the Division's position in these issues, please contact Mr. Trevor Clements or Mr. Arthur Mouberry at 919-733-5083. Should you feel your comments are not addressed in the issued permit, you may request an adjudicatory hearing in accordance with Chapter 150B of the General Statues of North Carolina within 30 days of issuance of the permit. i Si.ncerely,/ R.

Brown - Selma Terminal BARTLESVILLE, OKLAHOMA 74004 918 661-6600 PHILLIPS PIPE LINE COMPANY SELMA TERMINAL COMMENTS ON DRAFT NPDES PERMIT NC0032875 Phillips Pipe Line Company submits` the following comments on the draft NPDES permit for the Selma Terminal. General Facility Information Facility Function Phillips believes it is important to clearly understand the operations of the Selma Terminal so that appropriate effluent limitations and permit conditions can be established for the facility. Selma Terminal is a facility that receives refined petroleum products by pipeline, stores these products temporarily in product storage tanks and transfers these products to transport trucks of various distributors for eventual sale to the public. Selma Terminal does not refine, treat or otherwise process crude oil or any intermediate petroleum product. The facility, therefore, does not generate process wastewaters. Of course, occasional drainage of water from the product storage tanks may, at times, be included in the discharge. Selma Terminal discharges primarily excess stormwater that accumulates inside the diked storage tank areas. The terminal also discharges stormwater that falls onto the covered truck loading dock pad and the small quantity of water used at the facility to wash down the loading dock pad. Hours of Operation The facility is manned 5 days per week, 8 hours per day. Because the product loading system is automated, the facility is open 7 days per week, 24 hours per day to qualified distributors. Transport truck drivers are carefully trained to conduct loading operations at the Terminal in a safe manner. Additional training of these drivers is done at scheduled intervals so that loading operations are carried out safely. Stormwater System As previously mentioned, the product storage tanks are located within areas surrounded by earthen dikes. Two such diked areas, from which Outfalls 001 and 002 originates, exist at the Terminal. The primary purpose of these diked areas is to provide a containment area for the stored products in the unlikely event of a.tank rupture, line break or similar incident. As these areas retain the stormwater falling within the dikes, they occasionally must be drained of water so that their emergency product containment function is preserved. While such stormwater contacts the outside of the product storage tanks, piping and similar equipment, it does not come into direct contact with the stored product. Therefore, the chance of significant stormwater contamination is slight. Stormwater and washdown water from the truck loading dock is treated in an oil -water separator with the water effluent routed to the diked area from which Outfall 001 originates. It is possible that some hydrocarbon product remaining in the water effluent at a low parts per million range may contact stormwater accumulated in that diked area. Phillips believes that routing of Phillips Pipe Line Company, ' Selma Terminal NPDES Permit No. NC0032875 Page 2 such effluent to a diked area is environmentally sound in that it provides a temporary holding area for the separator effluent so that it can be visually checked for the presence of hydrocarbons prior to release. All waters released from the two diked storage areas are checked visually for the presence of hydrocarbon products prior to release in accordance with written procedures required by the facility's Spill Prevention, Control and Countermeasure (SPCC) Plan. Traces of floating hydrocarbons are removed prior to release. Phillips believes that in view of the low solubility of these products in water and the time allowed for physical separation of the hydrocarbon from the water in the diked areas, the terminal's discharges offer an extremely low potential for adverse impact on receiving waters. Comments on Specific Permit Conditions The following comments on the specific draft permit conditions should be considered in light of the above facility information and the limited potential for adverse environmental impactresulting from the facility's discharge. These comments apply to both outfalls 001 and 002 unless otherwise noted. A. Permittee Designation Selma Terminal is owned and operated by Phillips Pipe Line Company. Please change the permit's cover sheet to indicate that Phillips Pipe Line Company is the permittee rather than Phillips Petroleum Company. B. Acute Toxicity While Phillips supports the goal of limiting or, if possible, eliminating toxic discharges to the waters of the United States, we believe that reasonable judgement must be exercised in achieving this goal. Measurement of acute toxicity of wastewater is not a straightforward or precise technique. Acute toxicity testing is both a time consuming and costly procedure. Phillips, therefore, believes that acute toxicity testing should not be required of every discharger. Monitoring of effluent toxicity is appropriate for major municipal or industrial dischargers whose discharge may contribute significantly to the amount of toxic pollutants in a waterway. We do not believe that such monitoring is necessary or appropriate for a product terminal's discharge. The Selma Terminal's discharges are primarily stormwater and generally are only slightly contaminated. Such discharges do not contain process wastewater which could be a significant source of toxic pollutants. The Selma Terminal's stormwater effluent is a minor source of discharge to the receiving streams and does not represent a significant threat to the water quality of those receiving streams. Toxicity testing is not a mandatory requirement for NPDES permits. The Agency has the discretion to require whole effluent toxicity testing when appropriate. Phillips believes that whole effluent toxicity testing is appropriate only for potentially significant contributors of toxic pollutants. Clearly, Selma Terminal is not a potentially significant contributor of toxic pollutants to the waters of the State. Phillips Pipe Line Company. Selma Terminal NPDES Permit No. NC0032875 Page 3 Phillips encourages the State to prioritize its requirements for whole effluent toxicity testing in a manner consistent with other states and EPA Regional offices. Such prioritization, in descending order for toxicity testing requirements, follows: 1. Major industrial, municipal and federal facilities. 2. Selected minor industrial and federal facilities associated with toxic problems. 3. Selected minor municipal facilities associated with toxic problems. 4. Other minor municipal facilities. 5. Other minor industrial facilities. Phillips believes that Selma Terminal < should not be required to perform the i because: 1. Selma Terminal is not a major i 2. Selma Terminal is not a major c receiving streams. uos t category and testing to the 3. Selma Terminal is not a facility associated with toxic pollution problems. 4. Selma Terminal does not employ processes or operations that result in significant contributions of toxic pollutants to its discharges or the receiving streams. Phillips therefore requests that the requirement to perform acute toxicity tests on the first five discrete discharge events be deleted from the final permit. C. Phenols Phillips recognizes that the State maintains the following phenolic compound requirements for Class C waters: Phenolic compounds: only such levels as will not result in fish -flesh tainting or impairment of other best usage. Selma Terminal operations do not add phenols to the wastewater by any manufacturing process. Phenols exist in the facility's stormwater only to the extent that such stormwater comes into limited contact with hydrocarbon product. Since contact with hydrocarbon product is minimal, the potential for significant phenol levels in the stormwater should be very low. Since (1) the discharge from Selma Terminal is extremely infrequent, (2) the potential for significant phenol levels is low, and (3) Phillips is not aware of any evidence that indicates the facility's discharges have caused significant water quality problems relating to phenols, Phillips requests that the proposed numerical limitation for phenols be dropped from the final permit j Phillips Pipe Line Company. Selma Terminal NPDES Permit No. NC0032875 Page 4 and be replaced with a requirement to measure and report phenol concentration of the discharge. Such a requirement will allow the development of a good data baseupon which, if a phenol problem is indicated, the Agency may base a future revision of the permit. D. Settleable Solids The draft permit limits settleable solids in the Selma Terminal's discharge. This is a most unusual effluent limitation for a product terminal discharge. It may be appropriate to limit settleable solids for a municipal or industrial discharger which employs some type of biological treatment (or otherwise adds settleable type solids to the wastewater). However, Selma Terminal neither employs such treatment nor otherwise adds settleable solids. Here, the principal settleable solids are primarily inorganic particles such as soil or dirt (essentially nonvolatile suspended solids). In the diked areas, the stormwater is retained long enough for this material to settle. However, the stormwater is not retained long enough for algal growth or any other biological material to develop. Therefore, Phillips requests that the requirement to measure and report settleable solids and the specified effluent limitations for this parameter be deleted from the final permit. E. Turbidity As with the settleable solids effluent limit, this is a most unusual requirement for a terminal permit. Please refer to arguments presented for settleable solids as they apply to this parameter also. The specified turbidity requirement is adequately covered in the State's water quality standards which are applicable to all freshwater bodies in the State. It is not necessary to include the turbidity water quality standard as a permit condition. Phillips, therefore, requests that this parameter be deleted from the measurement and reporting requirements of the final permit. F. Acid and Base/Neutral Extractable Organics Purgeable Organics Napthalene Part III. Condition H It is unclear from the draft permit wording what is being proposed in Part III, Condition H. First, there is no "groundwater effluent discharge" from this facility. There are two surface discharge points as described in the General Facility Information above. Second, because of the intermittent nature of these discharges, it could be physically impossible to comply with the 60 day submittal requirement unless a significant rainfall event occurs which results in a discharge. Phillips does not believe that the nature of Selma Terminal's discharges warrants the monitoring of the full slate of parameters included in the Acid and Base/Neutral Extractable Organics or the Purgeable Organics. Phillips also does not believe the discharge warrants the monitoring of napthalene. Testing results from other Phillips' product terminals and from stormwater Phillips Pipe Line Company, • Selma Terminal NPDES Permit No. NC0032875 Page 5 effluents from Phillips 66 Company's refineries have showed that nearly every compound covered by these two groups are below the detectable limit of the test procedures. Phillips believes that monitoring of toluene, benzene and xylene is adequate for this type of discharge. Phillips can provide the test results that have been obtained for these product terminals and refinery discharges as supporting evidence of these positions if requested to do so. Phillips requests that Part III, Condition H of the proposed permit be deleted. Also, Phillips requests that the Acid and Base/Neutral Extractable Organics, Purgeable Organics and Napthalene be deleted from the effluent limitations and monitoring requirements for both discharge points. G. BOD5 Phillips does not believe that the BOD5 parameter is appropriate for these two discharge points. The organic content of the stormwater will be adequately monitored through the oil and grease test and by measuring the toluene, benzene and xylene content. Since the nature of the Terminal's operations does not contribute or add organic material to the stormwater except through the incidental contact of the stormwater with small quantities of product, the measurement of BOD5 is not justified. Futhermore, no treatment facilities specifically designed to reduce the BOD5 content are provided since there is no need to do so because of the low levels present. Therefore, Phillips requests that B0D5 be deleted from the effluent limitations and monitoring requirements for both outfalls. H. MBAS As with BOD5, Phillips does not believe the nature of the Terminal operations supports the need to monitor the MBAS levels in the two outfalls. Therefore, Phillips requests that MBAS be deleted from the effluent limitations and monitoring requirements for both outfalls.
