The continuance will allow the Colorado Department of Public Health and Environment(CDPHE)and the County to evaluate other potential enforcement actions in accordance with the Solid Waste Act. STATUS: HS Resources and Amoco have completed their portion of the cleanup required under the EPA Order. They nave committed to one year's maintenance of the cover over the areas that they have closed and revegetated. They have also committed to one year of additional groundwater monitoring. This will conclude in December 2000. The CERCLA (Comprehensive Environmental Response Compensation and Liability Act also known as Superfund) action will be completed in the next month. The EPA 'viii also monitor the cover over the areas that they have closed and revegetated and will monitor groundwater until December 2000. WI?#AT'S NEXT?: The remaining issues at this facility include,but are not limited to: ▪ Long-tern: (up to 30 years) maintenance and care of the cover. This includes assuring that a cover crop is established and maintained. • institutional controls to prevent excavation or structures in areas where residual contamination remains. • Long-term (up to 30 years) groundwater monitoring to demonstrate the quality of groundwater downgradiant from the facility. • Financial assurance for post-closure monitoring, maintenance and care. Ideally,these issues will be addressed through authorities available to the County and the CDPHE in the Solid Waste Act. In the event these issues cannot be addressed through these means, the County and the CDPHE will have to re-assess our options. ATTAC€€MENTS: Attached i= the memorandum that I provided to you last year. It provides information regarding the background of the facility, the EPA Order, and the CERCLA action. tj/wcwd/2000update 2000-0457 /t z//-' t: 0 . ft fc' MEMORANDUM TO: Weld County Commissioners DATE: rry 24, 1999 FROM: Trevor Jiricek, Health Departmen a COLORADO SUBJECT: Weld County Waste Disposal Our Department is recommending for a continuance for a period of one year for this Probable/Show Cause hearing involving the Weld County Waste Disposal. The characterization, remediation, and clean up of the site continues. The one year continuance will allow for further progress. Our Department has been following all of the activities and progress which has taken place at the Weld County Waste Disposal. BACKGROUND: The following is a very brief history and update of the activities that have taken place at the Weld County Waste Disposal (WCWD) and a summary of the status of the E.P.A. order: In the spring of 1995 our Department and the Weld County Planning Department had cited the WCWD for numerous violations of its Special Use Permit. As the result of these violations, the facility was in the County's Probable/Show Cause process. However, in May 1995, under the authority of Section 7003 of the Resource Conservation and Recovery Act, the Environmental Protection Agency issued an Order "to abate an imminent and substantial endangerment to health or environment..." to the Weld County Waste Disposal, owned by Howard Duckworth. The Order alleged that a groundwater impact had occurred which was attributed to the facility and that waterfowl had been killed as the result of landing on the oily surfaces of the ponds. The Order was also issued to the two companies which had disposed the largest quantity of waste at the facility. These two companies, Amoco Production Company (Amoco) and HS Resources Inc. (HSR), have since taken the lead in implementing the Order. The WCWD is located approximately 5 miles east of Fort Lupton. It had been in operation since the 1970's and primarily accepted liquid exploration and production waste for disposal by evaporation. The site consisted of a receiving sump where liquid waste was initially dumped upon receipt at the facility. The waste was then pumped into on-site tanks where any reclaimable oil was separated out. The waste was then discharged into two large ponds for evaporation. EPA ORDER: The Order and its requirements are broken up into several major sections. The three sections specifically dealing with site characterization and remediation are briefly summarized below. Weld County Waste Disposal February 24, 1999 Page 2 They are: I. INTERIM MEASURES - This required the respondents to submit an "Interim Measure Work Plan" which included, but was not limited to the installation of a security fence, posting of signs, a method to permanently eliminate any oily surfaces which may come into contact with wildlife, characterization of the extent of off-site ground water contamination, etc. This section also addressed immediate remediation of any impact to human health and the environment. Status: The interim measures are finalized. II. SITE CHARACTERIZATION - This required the respondents to submit a "Characterization Work Plan" to characterize the magnitude and full extent, both vertical and horizontal, of all contamination of soils and groundwater on and from the receiving facility and to assess the physical integrity of all waste management units and devices. Status: The on-site soils have been characterized. However, the off-site groundwater characterization work plan has not yet been approved by the E.P.A. Additional off-site groundwater characterization may still be required. III. SITE CLEAN-UP - This requires that the respondents submit a "Clean-Up Work Plan" which evaluates alternatives for the treatment and disposition of all contaminated media, including contaminated soils, ground water and other materials and debris. Status: An on-site closure work plan has been submitted and is currently under review. In general, for each major section, the respondents must submit a plan in accordance with strict submittal dates. The plans are reviewed by the County and State Health Departments, and the E.P.A. In addition, the respondents were required to develop a community involvement plan. This plan has been developed and implemented to the satisfaction of all of the Agencies. It included surveys, newsletters, and public meetings for interested parties. Other routine activities required by the Order include monthly progress reports to the agencies and the submittal of quarterly groundwater monitoring reports. CERCLA (Comprehensive Environmental Response Compensation and Liability Act also known as Superfund) REMOVAL ACTION: During characterization of the site, chlorinated compounds were detected in the soils beneath pond D (see attached site layout) and in the groundwater downgradient from the facility. Many Weld County Waste Disposal February 24, 1999 Page 3 of these same chlorinated compounds were also found in the groundwater downgradient from pond D. Chlorinated compounds are not typically found in exploration and production wastes. In reviewing historical aerial pictures taken of the site, HSR and Amoco discovered an older waste pond, now known as pond E (see attached photographs), that existed in the location (within the perimeter of pond D) where the chlorinated compounds were discovered. Waste was disposed in Pond E from approximately 1978 to 1980. It was then covered with soil. Pond D was constructed in approximately 1981, and operated until the facility closed in May 1995. Chlorinated compounds were also found in the area identified as the "former receiving area". This receiving area operated from approximately 1978 to 1984. Following detection of the chlorinated compounds and after review of the aerial photos, HS Resources and Amoco argued that they should not be responsible for the remediation of the impact from the chlorinated compounds as they did not dispose waste at the facility during the time period that pond E and the "former receiving area" were operated. They also argued that the chlorinated compounds are not typically found in exploration and production wastes. EPA agreed not to pursue the Order requirements at these areas at these times. However, the EPA was also of the opinion that the contaminated materials in pond E should be addressed in a timely fashion. As a result, EPA contacted their emergency response staff EPA assessed the site by collecting samples, etc. and found that the site warranted action under CERCLA. EPA determined that the site was appropriate for a non-time critical removal of the waste material. Currently, this removal action is scheduled for early April 1999. The removal action will consist of excavation of the soil and thermal treatment in a thermal desorption unit. Once treated the soil will be returned to the excavation. Treatment of the impacted soil should eliminate the source of the impact to the groundwater. However, additional remedial actions are currently being considered for groundwater emanating from the site. It should be noted that the EPA is only addressing those impacts from the chlorinated wastes disposed at the facility. HSR and Amoco will continue to address all other portions of the Order and clean up of the site. tj\1186 e r e f s � • ,%--•r01-v,.7 i xN" , y f uT' #0. v k /raw rf a sJ xx -tikto925?-', �'s , r pm�y cf.13 j4+.„e 7"r fW,..5 vJt r• 14,,,i,,,...).-:•;44.7,5:' t r '.^ ..a m .�+ S m. a}-' ,, y.F4 n� ` v.,ii404'' � « k tr'}° .,.
