�.f Comment on pg. 1, para. 4. This statement is erroneous. To date, the Department of Health Services (DHS) has not received a border zone request for the SPR property. Further review of the health risk assessment cannot proceed without this letter. Response to comment on Section 1, pg. 1, para. 4: A border zone determination request for APN 195-060-02, -03, -08, and -09 was sent to Mr. Allen Wolfenden, Chief, Technical Services Unit, from Mr. John T. Verner, owner of Verner Construction Company prior to April 6, 1989 (see Attachment 3). As indicated in "Response to comment on Section 1, pg. 1, para. 3:," above, the Segura Trucking Company site is not considered a hazardous site subject to border zone determination for the SPR property and subject HRA. Comment on Section 2.4 All toxic compounds likely to be contained in the disposal area should be identified and discussed. The possibility of migration of other fuel components via ground water should also be addressed. While monitoring soil gas for benzene is planned, Kleinfelder should be made aware that further sampling and analyses may be necessary, should the data so indicate. Kleinfelder should closely monitor the progress of the San Joaquin Local Health District's site assessment, and should inform DHS of the outcome of this assessment in a timely manner. Response to comment on Section 2.4: As indicated in 'Response to comment on Section 1, pg. 1, para. 3:," above, the Segura Trucking Company site is not considered a hazardous waste site subject to border zone determination for the SPR property. We will provide copies of our correspondences to both DHS and SJLHD. We assume we will also receive copies from both agencies to complete our file. Comment on Section 5.3 For a compound with no published DHS Toxic Substances Control Division Applied Action Level, U.S. Environmental Protection Agency (EPA) health-based criteria should be employed. Use of the EPA IRIS (Integrated Risk Information System) data base is recommended. "Target Concentrations" should only be derived when neither DHS nor U.S. EPA health-based criteria are available. Response to comment on Section 53: As requested, use of EPA IRIS (Integrated Risk Information System) data base will be employed for compounds with no DHS Toxic Substance Control Division Applied Action Level. Target concentrations will only be derived when neither DHS nor EPA health-based criteria are available. Comment on Section 5.4.3 Potential exposures attributed to the North Balloon Air Stripper should be estimated. KLELNFELDER 9795 Business Nark Drive, Suite C, Sacramento, CA 95827 (91i,) 36G1-'�l
