PCB concentrations in soil and sediment As polychlorinated biphenyls (PCBs) accu-mulate in the organic fraction of soil and sedi-ments, the PCB content of the sample will depend on the sample material. Total concentrations of 12 dl-PCBs in sediments ranged from 2.70 to 177 pg/g dry weight, with a mean value of 24.0 pg/g dry weight (Fig. DEC sampled nearly 1,700 locations—in many areas, the average PCB concentrations exceed the 1 part per million cleanup level typically used by DEC for sediment cleanup projects. • Once cleanup is underway, the EPA must be notified in writing of any changes to the proposed cleanup no . Sign Up. EPA recommends removing PCB-containing FLBs from buildings as soon as possible to prevent potential inhalation or dermal exposure. The Florida Department of Environmental Protection is the state’s lead agency for environmental management and stewardship – protecting our air, water and land. 1 b). The Guidance also discusses the requirements for verifying that cleanup standard have been met and for establishing deed restrictions where necessary as well as the options available for disposing of PCB wastes. Studies are still on-going to identify the possible sources of this contamination. For the reasons set forth in the memorandum, the Agency reexamined this interpretation and determined that it is not required under TSCA. Interested in subscribing to DEP newsletters or receiving DEP updates through email? (i) Contaminated solid surfaces (both impervious and non-impervious) shall be cleaned to a PCB concentration of 100 micrograms (µg)/100 square centimeters (cm 2) … The RODs authorized dredging, capping and sand covering as the remedial action methods. Ballasts manufactured through 1979 may contain PCBs. This fact sheet is intended to help answer questions regarding how to comply with EPA regulations for PCB-containing x-ray machines. The web pages below contain copies of select letters and memoranda issued by EPA headquarters (HQs) that contain guidance: EPA developed an interim guidance for conducting public engagement in the PCB cleanup, storage (prior to disposal) and disposal approval process during the COVID-19 public health emergency. (2) Removal of the fine organic sediments may also play an important role, since a … Overall, the average sediment PCB concentration varied significantly between different reaches of river, indicating there are still certain areas in the upper Hudson where PCB contaminated sediments remain. PCB levels above the Washington State Sediment Cleanup Levels were found in sediments at 0-2, 2-4 and 6-8 ft depths near the outfall of the Jorgensen pipe. A hazardous waste manifest is required for the transportation of PCB waste in accordance with 40 CFR part 761 subpart K. The eManifest FAQs contain information that may be helpful to entities creating and managing PCB waste manifests. PCBs are classified as persistent organic pollutants (POPs) with high toxicity, and have undesirable effects on the environment and on humans (Lallas, 2001). Although PCB levels were lower than those measured in 1994 and 1996, most fish tissue samples still exceeded the National Toxics Rule human health criteria (NTR=5.3 ug/kg). operated a large-scale industrial facility including the manufacturing and servicing of power transformers FDA's tolerance levels for PCBs in food range between 0.2 and 3 ppm. For specific regulatory and legal requirements, please refer to the PCB regulations at 40 CFR Part 761 (PDF). Dredging began in 2009 and was completed in 2015. That dredging the contaminated sediments was unsuccessful in lowering PCB levels in the biota may be for the following reasons: (1) Due to the low solubility of PCBs in the water it is possible that a decrease in the sediment concentration of PCB would leave the water concentrations of PCB unchanged. The document may be useful to Brownfields grant recipients or others revitalizing old properties that involve PCB cleanups under TSCA. PCB cleanup makes uneven progress ... A study that Ghosh and other researchers presented to the district earlier this year found dissolved PCB levels in the creek to be “screaming high,” as he put it — up to 20 times the levels measured in the river. Sampling of surficial sediments conducted in 1996 indicated moderate levels (typically < 25 mg/kg) of PCB contamination throughout the harbor from the North Harbor down to the Entrance Channel. The purpose of the PCB Penalty Policy is to ensure that penalties for violations of the various PCB regulations are fair, uniform and consistent, and to deter people from committing PCB violations.

ø °!`.Ó5¦13@|DC&_´ø¹ñ\ÈB^?Ì°&³O7ü¾ä¥ùÜóýÜs^Aª => When EPA identifies violations of the PCB provisions of TSCA, EPA responds to such violations in accordance with the April 9, 1990 PCB Penalty Policy. EPA is interpreting its PCB regulations under the TSCA to generally allow for recycling of plastic separated from automobile and other shredder residue. Future updates will be posted here, and each update will be noted in the revision date of the Manual. This guidance does not replace or supplant the requirements of the TSCA PCB regulations, nor does it establish a presumption against enforcement should any violations of PCB cleanup and disposal regulations be discovered. Even intact PCB-containing FLBs may emit small amounts of PCBs into the air during normal use. Furthermore, it is the Agency's position that recycling material that would otherwise become waste can generate a host of environmental and economic benefits while protecting people's health. The Guidance also discusses the requirements for verifying that cleanup standard have been met and for establishing deed restrictions where necessary as well as the options available for disposing of PCB wastes. Although the letter is specific to AGA's circumstances, we believe it will be helpful to many natural gas utilities that use MDPE and HDPE in their distribution systems. Sediment The cleanup level established for PCB-contaminated sediment may be based on direct-contact threats (if the surface water is used for swimming) or on exposure as sumptions specific to the site (e.g., drink- ing water supplies). The approved remedy for OUs2-5 was to remediate all sediment with PCBs greater than 1 ppm by … For sediments, fine material is generally preferred (OSPAR, 2002). This document supplements the Environmental Protection Agency’s “Planning for Natural Disaster Debris Guidance” to provide more detailed information on the management of PCB-containing disaster debris in emergency situations that arise from natural disasters. PCBs were commonly used in the small capacitor within fluorescent light ballasts. • Sediment PCB concentrations ranged from 0.46 to 3.95 ug/kg. According to EPA Toxic Substances Control Act (TSCA) regulations, the material must be incinerated. . In 2007 and 2008, ROD Amendments were issued for OUs2-5 and OU1, respectively. These proposed cleanup goals will protect people and the environment. EPA responded to AGA with the determination that MDPE and HDPE used in natural gas distribution piping may be considered a “non-porous surface” as defined in 40 CFR 761.3, and may be wipe sampled as such for waste profiling. The Agency believes this interpretation responds to stakeholder interest in the use and distribution of recycled plastics from shredder residue recovered from metals recycling facilities. EPA's enforceable MCL for PCBs in public drinking-water systems is 0.0005 ppm. The concentration of PCBs in walleye and sediment in Little Lake Butte des Morts has dropped significantly following the $92 million government-ordered cleanup of the lake. Mean concentrations of CB118 in sediment are at or above this level in three of the six assessment areas assessed. Total PCBs in sediments were much lower than the sediment cleanup objective (110 ug/kg) described in WAC 173-204. A transformer on the Boeing Plant 2 site just north of the Jorgensen Pipe was identified as one likely source of contamination. EPA responded to US Ecology clarifying the intersection between the PCB regulations and the RCRA regulations with regard to specific forms of treatment. Docket EPA-HQ-OLEM-2018-0305 on regulations.gov. Environmental monitoring conducted during cleanup activities in 2004 and 2005 has shown that contaminated sediment removal is being done without an appreciable release and downstream loss of PCBs. PCB-containing FLBs that are currently in use have exceeded their designed life span. EPA’s Response Letter to AGA Regarding MDPE and HDPE as a Non-Porous Surface, the Office of Land and Emergency Management web page, the Office of Chemical Safety and Pollution Prevention web page, PCB Cleanup and Disposal Guidance in Interpretive Letters Issued by EPA HQs, PCB Cleanup and Disposal Guidance in Memoranda Issued by EPA HQs, Facility Approval Streamlining Toolbox (FAST), Commercial Storage and Disposal Facilities, 2004 Supplemental Response to Comments Document on the Proposed Rule - Disposal of PCBs, The extent of potential or actual environmental harm from a given violation, Trial burn and demonstration (demo) test plans; and. EPA received a letter from the American Gas Association (AGA) in March of 2018 requesting that EPA clarify whether or not Medium Density Polyethylene Pipe (MDPE) and High Density Polyethylene Pipe (HDPE) are non-porous surfaces. Interim sediment quality criteria PLANS FOR PCB CLEANUP IN A REGIONAL SEWER; Share This. The 2019 Guidance for Applicants Requesting To Treat/Dispose of PCBs Using Incineration or an Alternative Method is an update to two versions from 1986. OMC dredged the northern harbor area to achieve a cleanup level of 50 mg/kg for PCBs. RODs were issued on the project: the first ROD was in 2002 for OUs1-2, and the second ROD was in 2003 for OUs3-5. Without cleanup, it would take decades if not hundreds of years, before PCB concentrations in fish would decrease to a level that would permit unlimited consumption. It is for persons applying to EPA for approval to dispose of PCBs using thermal and non-thermal alternative methods (40 CFR 761.60(e)) or incineration (§ 761.70). GE/Housatonic River Site Update (PDF) (PDF) (6 pp, 700 K, About PDF ) on how PCBs move through the environment, what EPA knows about the PCBs in the Housatonic River, and their health effects. With the exception of the most toxic congener (CB118), concentrations of all PCB congeners in sediment are below the level at which they could present an unacceptable risk to the environment. AGA provided a study titled Assessment of Polychlorinated Biphenyls (PCBs) in Polyethylene (PE) Gas Distribution Piping conducted by NYSEARCH and National Grid, which demonstrated that the amount of PCB absorption into MDPE and HDPE was minimal, and penetration of PCBs was not beyond the immediate surface.
