RECOMIKENDATIONS 1. Request the Bay Area Air Quality Management District' s Hear- ing Board (BAAQMD) to arrange for the odor control programs for the Shell and Tosco refineries wastewater treatment ponds, which the BAAQMD is about to require through abate- ment orders, to be closely monitored by the District; and, accordingly, request the BAAQMD Hearing Board to arrange for the District to notify the County of odor episodes noted by BAAQMD staff or reported by complaints, and provide copies of reports on the programs to the County; and 2. Request the BAAQMD Hearing Board to require the use of Best Available Control Technology in the plan for enclosing the Shell Oil Company' s refinery wastewater treatment system, which the BAAQMD is about to require through an abatement order, prior to approving the enclosure plan; and, request that the BAAQMD Hearing Board enable the County to review and comment on the plan prior to its approval; and 3 . Request the BAAQMD Hearing Board to enable the County to review and comment on an enclosure plan for the Tosco refinery' s wastewater treatment ponds if the Hearing Board orders its preparation; and 4 . Authorize the Community Development and Health Services Departments to prepare, for Board of Supervisors considera- tion, a policy calling for the enclosure of industrial wastewater treatment systems, to complement the Board' s policy on the elimination of open pon for treating hazardous wastes.

BACKGROUND On April 26, 1990, the Hearing Board of the Bay Area Air Quality Management District held public hearings in Martinez to take testimony on proposed abatement orders concerning the Shell and Tosco refineries ' wastewater treatment ponds that the Hearing Board is considering adopting on May 9, 1990. Copies of the proposed abatement order were not available prior to the hearing. The County Community Development Department appeared at the Shell hearing and requested the opportunity to review both the proposed short-term abatement program and the long-term enclosure plan, addressed in the abatement order, and the opportunity to take the matter to the Board of Supervisors. BAAQMD Hearing Board proce- dures, however, required testimony to be introduced at the hearing, but we believe that the proposed recommendations to the Hearing Board will receive consideration because they address the subsequent implementation of the Hearing Board' s abatement orders. Staff recommends that the Board of Supervisors request the BAAQMD Hearing Board to arrange for the District to monitor the short- term abatement programs and make information on it available to the County. We are basically concerned that the abatement programs be monitored and made to be effective, rather than the refineries simply made responsible for implementing a specific program whether or not it is working well. In particular, we want the program to be effective, or made to be effective, during the hot season of the year. With respect to the Shell refinery, we are also concerned that the short-term abatement program be superseded by the long-term (enclosed system) solution as soon as practicable. A deficiency with the BAAQMD Hearing Board' s draft abatement order, as we see it, is that the abatement order sets a time for the submission of the enclosure plan (December 10, 1990 ) , but not a deadline for its implementation. Accordingly, we recommend that the Board of Supervisors ask the Hearing Board for the opportunity to review and comment on the plan in draft form. The third recommendation, as noted in its text, is for staff to draft a policy for Board of Supervisors' consideration extending the Board' s past policy on the elimination of toxic waste ponds to include unenclosed industrial wastewater treatment ponds. Copies of the BAAQMD' s draft abatement order for the ; Shell Oil Company refinery are being provided to the Board of Supervisors ' members. We have not yet received the draft abatement order for the Tosco refinery. jl47:baagmd.brd 2.

Respondent and the District have agreed 9 to this Stipulated Amended Conditional Order for Abatement to 10 i resolve the issues raised in the District' s Accusation. The 11 Order includes short term and long term corrective actions with I � 12 a compliance schedule and increments of progress. ;3 On April 26, 1990, the matter came on for hearing. Toby 14 r: Sherwood, Assistant Counsel , appearing for the Air Pollution I; 15 ii Control Officer, and Keith Howard appearing for Respondent, and 16 ` all persons interested in the matter wishing to be heard having �! been heard, and the matter having been taken under submission for 17 ,: ' i 18 ! decision; i 19i The Hearing Board states as the reasons for its decision, 1 20 and finds as to those matters in which its findings are required, 21 that 22 1 1. Notice of this hearing has been given for the time and 23in the manner required by law, and, in particular, by sections ?4 40823 and 42451 of the Health and Safety Code, and the hearing I 25 was conducted in accordance with the terms of said provisions of 26 � the Health and Safety Code. 2 I i i o 2. The District contends that Respondent is discharging 2 odorous emissions from its Martinez Manufacturing Complex which 3 creates a public nuisance in the community downwind from 4 Respondent. Respondent disputes that contention. 5 3 . Members of the public were given an opportunity to 6 testify, and several testified. 4 . Respondent is the owner and operator of an oil refinery 8 and manufacturing complex located in the City of Martinez, and 9 ' Contra Costa County, California. I 7p i 5. Aspart of Respondent's manufacturing business, Respondent operates a waste water treatment system that has the i2 potential to emit air contaminants. Potential sources within the s t 3 Y open 1; system include o ponds 1-4 and 6, the biotreater, dissolved i. t 4 ! air flotation unit, the API separator and the sludge thickener. 15 • The District contends that odors emitted from these sources i ,6 , have caused violation of Reg. 9, Rule 2 , section 301 and have I: caused detriment nuisance and annoyance to a considerable ;7 Y 18 number of persons and the public and have a natural tendency to 19 cause injury or damage to business or property in violation of 20I District Regulation 1-301 and Health and Safety Code section I1 21Ij 41700. Respondent has denied each and every contention. 22 ,i 6. The parties agree that Respondent has embarked upon a 23 I program to identify odor sources and corrective action in order i 24 ' to effect a permanent resolution of the alleged violations and I 25 nuisance odors. Further, the parties agree Respondent has 26 � undertaken and shall continue to undertake the interim control 3 1 i 1 measures and short-term and long-term measures to reduce and 2 control alleged odorous emissions, including appropriate time 3 schedules and increments of progress. 4 7. Respondent employed the consulting firm Brown & 5 Caldwell to undertake a study to identify sources of odors from 6Ithe waste water treatment facility and assess short and long term solutions for control. The study concluded the primary odor i 8 emission source that contributed to detectable odors is sludge 9 in ponds 1, 2, 3 , 4 and 6. 10 8. Respondent, commencing in June of 1989 , and continuing 11 to date, has undertaken a number of interim measures and short- ,2 term measures to reduce and control alleged odorous emissions 13 from its waste water treatment facility, specifically including those items listed in paragraphs A. 1. through A. 8 . of this Order. I � 15 Respondent has further committed to the activities and increments j 16 : of progress set forth in paragraph B. 1. of this Order. 17 9. Pursuant to the provisions of California Health and 18 Safety Code §42451 (b) , the Complainant (District) and Respondent i. 19 '; have stipulated to the terms and conditions of this Conditional 20 Abatement Order without the necessity of this Board making a 21 I finding of violation of Health and Safety Code §41700 or 41701. 22 NOW THEREFORE, the Hearing Board ORDERS: 23 That 'Respondent, Shell Oil Company, Martinez Manufacturing 24 Complex (Respondent) , abate odorous emissions from its wastewater 25 treatment facility in accordance with 'the following terms and 26 conditions: I 4 I . i I A.

ENVW#ONWNTAL SYSTEMS.INC. ce er 26, 198-9 had a mild hydrocarbon odor, but no detectable hydrogen sulfide odor. Acidifying the sample released _& small amount of hydrogen sulfide indicating that sulfides are present in the sample, probably as FeS. In order to get a more precise idea of the sludge 's composition, a sample was sent out to a local lab for several tests. The results are expected by January 5th and will be forwarded to the District as soon as they are available. Global Environmental Systems, Inc. will act as the general contractor for this project and will be responsible for super- vising and scheduling all dewatering and dredging activities. Global has tentatively selected the road immediately south of Pond 6 as the site for all the dewatering and sludge storage equipment . At present, Global and Shell have: agreed to proceed with equipment mobilization and have scheduled January 15th as the first day of dewatering and dredging operations. Global has arranged to use two large filter presses for the dewatering work and will be generating 130-140 tons per day of filter cake in 14 to 18 dumpboxes. The large dewatering equipment, which is rate- limiting, has been selected to complete the removal and dewa- tering of 200-250 thousand barrels of pond sludge in approxi- ninety days of round-the-clock operation. ODOR ABATEMENT PROGRAX: Global Environmental is aware that there have been odor com- plaints, outside the refinery, downwind of Pond 6. It is be- lieved these odors are caused by minute levels of airborne mercaptans and other reduced sulfur species Formed by anaerobic activity in the pond sludge . Shell has stipulated that Global perform the dredging and dewatering work without causing addi- tional odors and maintaining H?S levels at Shell 's fenceline of less than 30 ppb. Global is concerned that :its operations may be singled out as the cause of any odors detected during the project and will conduct its own monitoring program Ito discover potential odor sources. Global will abate these sources to the maximum practical extent and is committed to the odor prevention steps described below. Global 's odor protection measures will include the following: I . Maintain a one to two foot water blanket over all parts of the pond that are being dredgeu. 2 . Survey the approximately 8 acres of pond surface to ascer- tain the areas with the deepest sludge and dredge those areas first. 3 . Operate the dredge only during daylight hours . 2 ' i C(1 GLOBAL . - -- - ENVVIONNIENTAI_ SYSTEMS.INC. December 26, 1989 4 . Use a Jerome Hydrogen Sulfide analyzer to assist and supple- ment Shell's HrS monitoring program (see attached procedure) that is conducted every four hours at five points around Shell 's Effluent Treatment Plant. In addition, Global 's site supervisor will conduct similar checks at areas down- wind of the dewatering equipment at the beginning and end of each 8-hour shift, twenty-four hours per day. 5. Global will make extensive use of ferric chloride for chemically abating odors. Ferric chloride acts as an oxidizing agent to destroy reduced sulfur compounds such as mercaptans and sulfides. Global will work with Shell to adopt a daily program of batch ferric chloride additions to Pond 6. This will include a minimum of one FeC13 addition, at the beginning of each day, in the pond areas to be dredged. 6. Global will be adding 40-42% ferric chloride solution at a 2-3% dosage to all sludge going to the filter press. It has been found that this ferric chloride , in combination with lime, acts as an excellent sludge conditioning agent to insure optimum dewatering via pressure filtration. Since ferric chloride will also act to chemically abate sulfide odors , this method was selected over more conventional sludge conditioning methods, e.g. diatomaceous earth. 7 . As the ferric chloride will destroy most odor producing compounds upstream, Global has elected to cover the filter presses for weather protection only and allow them to be naturally ventilated. The filter presses will only be Opened for twenty to thirty minutes during each 1-2 hour cycle to drop the filter cakes. 8 . Global will ensure that all 20 cubic yard dumpboxes have their tops closed, or are covered, once they have been filled with filter cake. Baker Tanks will be abated as provided below. 9 . In accordance with past Bay Area AQMD permits, Global will monitor its equipment once per shift with a portable FID hydrocarbon analyzer and a hydrogen sulfide analyzer sensi- tive down to 1 vppm of either species. Global agrees to abate any vapor sources containing hydrocarbons at levels above 10 vppm (excluding methane) , measured as methane- equivalent, or hydrogen sulfide above 1 vppm. Global will abate these sources by venting them through one or more 55 gallon, activated carbon canisters. 3 Pr) R(1V nPs'200 ron�1 SAO-Q4A' -V•► SUPV, FA DEN , MT2 TEL No .415-646-1396 Apr 30 ,90 16 :31 No .016 P .02 .

BACKGROUND: Waste water ponds at central county refineries have been a long-standing source of odor problems. The Board previously took a position supporting elimination of hazardous waste ponds and it' s time to now consider whether it is in the best interest of county residents to continue ponding of waste water or move to an enclosed tank system. The air district hearing board is considering enforcement action under an abatement order at this time, and will take testimony for two weeks from April 26th.
