SUPERFUND Records Of Decision Update From: Hazardous Site Control Division To: EPA Regional Offices June 27, 1985 Vol. 1, No. 2 ROD SUMMARIES CHARLES GEORGE, REGION I, MASSACHUSETTS (Approved 12/29/83) Description: Leachate from a chemical waste landfill contaminated residential wells with VOCs and other organics. Decision: Operable Unit: extend an ex- isting water supply system to private residences with con- taminated wells. Future remedial actions to be de- cided after the RI/FS is con- ducted. Issues: Extension of a water line from a municipal supply was determined to be the most cost-effective alternative. The closest town had an ample supply but was unwilling to provide the water. The state had no authority to force the town to do so. Therefore, the next closest town that was willing to cooperate was chosen to provide the water. Contact: Region I: Rick Leighton FTS: 223-1946 Headquarters: Bill Kaschak FTS: 382-2348 BRIDGEPORT, REGION II, NEW JERSEY (Approved 12/31/84) Description: PCBs and organics found in abandoned waste oil storage and recovery facility. Decision: First operable unit: dispose of oily waste and sediment/ sludge via onsite incinera- tion; remove and dispose of contaminated water via on- site treatment system. Issues: Incineration was the only alternative that could protect human health and the en- vironment. Because onsite containment and offsite disposal remedies were not adequately protective, there was no need to fund balance. Onsite, rather than offsite, in- cineration was preferred bas- ed on cost evaluations; however, competitive bidding will decide which incinera- tion alternative (on or offsite) will be used. Selection of the final cleanup levels was deferred until completion of a subsequent RI/FS. Contact: Region II: Ron Barsolino FTS: 264-1913 Headquarters: John Kingscott FTS: 382-7996 FRIEDMAN PROPERTY, REGION II, NEW JERSEY (Approved 4/30/85) Description: Dumping of municipal refuse, bulk liquids, household and demolition debris. Decision: Since there was no signifi- cant contamination remain- ing at the site and no Region/HQ Procedures for Incorporating Newly Signed RODs inlo the Distribution System 1. Once a ROD is signed by the RA/AA, send a copy, which is not only legible but reproducible, to the Program Manager in HSCD/HQ. 2. HQ Program Manager is to provide a copy to Lori DeRose on the RAB staff (phone: 382-3304). 3. Copies will then be made for the monthly distribution to the Regional Counsels & SF Managers; also sent to NTIS and ELI. Inside: Page 3 'A Line on RODs" ------- evidence of contaminant migration, the no-action alter- native was chosen. Issues: There is no reliable evidence to indicate "that hazardous wastes were ever disposed of at the site. Thus, the site was evaluated as a solid waste dump under RCRA Subtitle D criteria, rather than as a hazardous waste disposal site under RCRA Subtitle C. (If hazardous waste had been disposed of, Subtitle C ap- plication would have been relevant). Contact: Region II: Don Lynch FTS: 264-8216 Headquarters: Bob Quinn/ Jim Spatarella FTS: 382-7995 HELEVA LANDFILL, REGION III, PENNSYLVANIA (Approved 3/22/85) Description: Landfill accepted high volumes of TCE wastes from local industries, resulting in soil, surface-water and groundwater contamination. Decision: Operable unit: contain, pump, and treat the source of con- tamination. Provide alternate water supply to local users and defer action on offsite plume in fractured bedrock. Issues: Final protection standards for groundwater will be deter- mined at a later date since ef- fectiveness of treating con- taminated groundwater in fractured bedrock cannot be established at this time. Effectiveness of groundwater treatment will define need for future action at the site. Contact: Region III: Bill Hagel FTS: 597-3161 Headquarters: Lisa Woodson FTS: 475-8246 LACKAWANNA REFUSE, REGION III, PENNSYLVANIA (Approved 3/22/85) Description: Strip mine pits used as a commercial/municipal land- fill contain about 15,000 buried drums of hazardous waste. Decision: Remove material from con- taminated cell and dispose of offsite. Cap remaining por- tion of the site that contained municipal waste. Issues: One option for dealing with sites where hazardous waste was disposed of in one por- tion and municipal wastes in an adjoining portion may be to use Subtitle C re- quirements to evaluate the former areas and Subtitle D requirements for the latter. Use of Subtitles C and D to evaluate a single site should be coordinated with the Regional Counsel and HSCD.

Last month the following was sent to the Superfund Coordinator and Counsel in each Region: A bound set of all the FY'82-85 RODs completed so far Abstracts for all the signed RODs A keyword index of over 300 words to all the RODs See your Superfund Coor- dinator or Regional Counsel to borrow and make a copy of any of the above informa- tion. BYRON/JOHNSON SALVAGE YARD, REGION V, ILLINOIS (Approved 3/13/85) Description: Surface and buried drums contaminated soil and groundwater. Decision: First operable unit: offsite disposal of all surface and buried drums as well as highly contaminated soil down to bedrock. Issues: Possibility of onsite contain- ment ruled out because of locational factors (fractured bedrock, subsidence). Contact: Region V: Karen Waldvogel FTS: 886-9292 Headquarters: Kitty Taimi FTS: 382-2449 Paul Schumann FTS: 475-6705 MOTCO, REGION VI, TEXAS (Draft Approved 2/14/85) Description: Seven unlined borrow pits contain four major types of wastes in layers of sludges and tars, 7 million gallons of organic liquids (including PCBs), and water containing metals and organics. Decision: Operable unit: remove and in- cinerate contaminated sludges and liquids. Issues: PCB concentrations in the large lagoon made incinera- tion the only cost-effective solution. Decision on how much lagoon sludge material to remove and incinerate was based on the need to main- tain structural integrity of the lagoon backfill and cover. Second operable unit will evaluate impact of remaining contaminants on ground- water quality. ------- Contact: Region VI: Don Porter FTS: 729-9712 Headquarters: Randy Kaltreider FTS: 382-2448 TIMES BEACH, REGION VII, MISSOURI (Approved 1/13/84) Description: The five Times Beach sites are contaminated with TCDD greater than 1 ppb. Decision: Excavate and place TCDD- contaminated soil in interim storage facility at Times Beach. Issues: Flood plain and wetlands assessments (Executive Orders 11988 and 11990) are required when those resources are impacted by alternatives discussed in the RI/FS. Contact: Region VII: Steve Wilhelm FTS: 758-7133 Headquarters: John Kingscott FTS: 382-7996 MOUNTAIN VIEW/GLOBE, REGION IX, ARIZONA (Approved 6/2/83) Description: Residential subdivision was built on graded asbestos tail- ings and asbestos- contaminated soil. Decision: Relocate residents per- manently; demolish and bury onsite all mobile homes and sewage treatment plant; close site by capping and fen- cing. Issues: It was more cost-effective to buy and dispose of mobile homes onsite, allowing residents to purchase replacement housing, than to decontaminate the trailers. Contact: Region IX: Jerelean Johnson FTS: 454-7515 Headquarters: Steve Hooper FTS: 475-8246 STRINGFELLOW ACID PITS, REGION IX, CALIFORNIA (Approved 7/17/84) Description: Thirty-four million gallons of toxic waste were disposed of at the site, inluding heavy metals, acids, and organics. Decision: First operable unit: installa- tion of an onsite system of extraction wells and pretreat- ment plant, followed by discharge to POTW system. Issues: Discharge to POTW required that the pretreatment system meet stringent local stan- dards. Contact: Region IX: Brian Ullensvang FTS: 454-8917 Headquarters: Bill Samuel FTS: 382-2450 Paul Schumann FTS: 475-6705 TACOMA WELL 12A/COM- MENCEMENT BAY, REGION X, WASHINGTON (Approved 3/1/83) Description: VOC contamination in City of Tacoma's Well 12A. Decision: First operable unit: pump and treat water from Well 12A to confine contaminant move- ment within aquifer. Issues: Deferred ACL decision allowed to start cleaning groundwater before esta- blishing final groundwater protection standard. Later monitoring will determine how long to pump, and the final target levels for ground- water cleanup. Waste and sludge was ex- cavated and an additional 15% of contaminated soil was removed to allow for a reasonable safety factor. Waste removal was partially justified by the resultant in- crease in long-term effec- tiveness of the groundwater flushing system. Contact: Region X: Phil Wong FTS: 399-7216 Headquarters: Steve Hooper FTS: 475-6689 A Line on RODs - MAJOR BREAKTHROUGH WITH RCRA ... If contami- nants have migrated from the site, and you propose an onsite remedy, you may consolidate the waste onsite without being considered a generator. There are, however, some conditions ... Call J. Bill Hanson (HQ, FTS-322-2345) for more infor- mation. BREAKTHROUGH #2 WITH RCRA ... You may now con- sider a level above background for cleanup and be consistent with RCRA. You can do a site- specific exposure analysis to establish that remaining con- taminants are not harmful to public health and the environ- ment. The RCRA delisting model is one way to establish safe levels. For those of you who attended the ROD work- shops at HQ or Regions V or VI, this was the approach discuss- ed. For details call Paul Schumann (HQ, FTS-382-2339). ADVANCED TECHNOLOGY ... for removal of volatiles from soil use a "D-6 cat" and a "two gang plough." What about control of emission rates dur- ing construction? Regions V and X are looking at other methods to control the rate of release. For more information call Phil Wong in Region X (FTS-399-7216) about the pro- posed plan for Well 12-A or Rich Bartelt in Region V (FTS-886-7570). This new method may involve considera- tion of patent rights; Nancy Willis (HQ, FTS-382-2347) is ------- checking into this. A NEW TECHNOLOGY ... Are you sure that it will work? How do you prepare a ROD when you are not sure of the new remedy? Call Region VI on this issue, and see how they handl- ed the Old Inger, LA site ROD, which involved land treatment of waste. MINE POOLS AND KARST FORMATION . . . How do you monitor groundwater contami- nation if an on site remedy is proposed? Are you responsible for contamination of the aqui- fers? OGC says yes. But how do you know the Superfund site is the sole contributor? You don't .. . This is a big issue; if you have one of these let's discuss ... (call Linda Boornazian, HQ, FTS-382-7997). IS CERCLA TOTALLY RES- PONSIBLE ... for cleanup of the aquifer if the areawide groundwater pollution is not caused solely by an NPL site? This too is a big issue and will be raised to upper manage- ment for resolution .... Con- tact J. Bill Hanson, HQ, FTS-382-2345. PCBs .. . For those of you who have sites with PCBs (and we know there are at least 10 sites with PCBs out there), new levels are now being devel- oped. We should use lower levels to be consistent with OTS and ORD recommenda- tions. We will be in touch on this ... but keep in mind that a bulldozer or backhoe is only ac- curate within 0.3 foot of a target depth. (Contact Paul Schumann, HQ, FTS-382-2339.) A GARBAGE DUMP . . . Do you know of a garbage dump that has had no hazardous wastes dumped into it? Are you con- sidering a Subtitle D closure? Contact Don Lynch (Region II, FTS-264-8216) for more infor- mation. MOVING ON ... As many of you know, Sam Knott is leaving EPA and will be working for PRPs!!! While he was with the Agency he assisted in the reso- lution of a number of very irrn portant issues. Unfortunately, we cannot recognize him for them at this time, because they are cloaked in Enforcement ne- gotiating documents. Someday we will all know ... but in the meantime: THE BEST OF LUCK SAM!!! ("A Line on RODs ..." is in- tended to provide quick helpful bits of information to Super- fund staff members regarding technology or other pertinent matters. The intent of these brief notations is to point those interested in the right direc- tion, either to a contact person or a particular ROD. If you have any information of this kind that would be helpful to others, phone it to Lori DeRose, HQ, FTS-382-3304.)
