The regulations establish performance standards that require each facility’s groundwater monitoring program to have a sufficient number of wells installed at the appropriate locations. Monitoring and reporting for public water systems that operate wells. About one-quarter of Wisconsin's population drinks water drawn from over 800,000 private wells. The first step in this process is establishing a groundwater protection standard (GWPS). While the interim status regulations do not contain corrective action provisions, the EPA Regional Administrator may order cleanup under RCRA §3008(h) or §7003 authority, or when the facility permit is issued. The owner/operators must then continue to monitor the groundwater quality. If an SSI in any constituent is detected and confirmed during sampling, the owner/operators must submit written notification to the EPA Regional Administrator in writing within seven days. Publications and guidance, Ground Water Rule and rules for well casing, well siting. An official website of the United States government. The facility must continue corrective action until the GWPS has not been exceeded for three consecutive years. This form must be utilized in conjunction with a Field Boring Log Form.

The list of hazardous constituents for which to monitor (from Part 261, Appendix VIII). Immediately sample all wells for 40 CFR part 264 Appendix IX constituents. Well Construction and Operation Guidance on well construction and operation for public water system operators. Tolerance or prediction interval procedure. Submit an engineering feasibility plan for a corrective action program within 180 days.

Samples are taken from the monitoring wells and analyzed for specific indicator parameters and any other waste constituents or reaction products that indicate that a release might have occurred.

At which point, the facility may return to compliance monitoring. At a minimum, four samples must be taken from each well semi-annually. State of Illinois Coronavirus Response Site. The facility must also analyze samples for part 264 Appendix IX constituents at least annually. The regulations for permitted facilities are found at Title 40 of the Code of Federal Regulations (CFR) part 264, subpart F – Releases from Solid Waste Management Units, and the interim status regulations for facilities in operation before these rules came into effect are found at 40 CFR part 265, subpart F – Groundwater Monitoring. 2. Illinois Pollution Control Board site you will find the appropriate regulations (under title 35 of the Illinois Administrative Code) for the following topics: It looks like your browser does not have JavaScript enabled.

An interim status facility subject to the groundwater monitoring requirements must design and implement a groundwater monitoring system capable of representing the background groundwater quality and detecting any hazardous constituents that migrate from the hazardous waste management units. Contact Us to ask a question, provide feedback, or report a problem. Unlike public water systems, the protection and maintenance of a private well is largely the responsibility of homeowners. View up to date information on how Illinois is handling the Coronavirus Disease 2019 (COVID-19) from the Solid Waste Landfill Groundwater, Leachate, Facility and Gas Reporting Form (LPC-591) RCRA Facility Groundwater, Leachate, and Gas Reporting Form (LPC-592) List of Monitoring Constituents … The frequency of sampling is determined by the EPA Regional Administrator and specified in the modified facility permit. The phases are sequential with a facility able to move back and forth between phases as certain criteria are met. For permitted TSDFs, a groundwater monitoring program consists of three phases: detection monitoring (40 CFR section 264.98), compliance monitoring (40 CFR section 264.99), and corrective action (40 CFR section 264.100).

The major differences being: Even with these differences, the overall goal of these requirements is the same: protect the groundwater in the uppermost aquifer from contamination by the hazardous constituents managed at the TSDF. The specific sampling requirements and procedures (including frequency of sampling) are specified in the facility’s hazardous waste permit.



Monitoring Well Construction and Abandonment Guidelines (March 2011) NMED Risk Assessment Guidance for Site Investigations and Remediation (Current document) Table A-1: NMED Soil Screening Levels: Synthetically Lined Lagoons – Liner Material and Site Preparation Guideline (May 2007) Gray Water Guide and Regulations Please turn on JavaScript and try again. The phases are sequential with a facility able to move back and forth between phases as certain criteria are met. The program must also address the type of waste management unit and the characteristics of the waste being managed. While land disposal restrictions and unit specific standards seek to reduce the toxicity of waste and prevent releases, respectively, the groundwater monitoring requirements represent the last line of defense by ensuring that any releases are detected and remediated in a timely manner. One completed form must be submitted for each groundwater monitoring well installed. The point of compliance, which is the vertical surface at which the facility must monitor the uppermost aquifer to determine if the GWPS is being exceeded. (c)1. As stated above, a facility must submit a permit modification application to switch from detection monitoring to compliance monitoring when an SSI is detected. The EPA Regional Administrator will approve the facility’s selected corrective action method and specify the time frame in which it must take place. Nonparametric analysis of variance based on ranks. Interim status waste piles are not subject to the groundwater monitoring requirements. United States Environmental Protection Agency, Title 40 of the Code of Federal Regulations (CFR) part 264, subpart F – Releases from Solid Waste Management Units, 40 CFR part 265, subpart F – Groundwater Monitoring, Handbook of Groundwater Protection and Cleanup Policies for Resource Conservation and Recovery Act (RCRA) Corrective Action, RCRA Training Module: Introduction to Groundwater Monitoring, RCRA Orientation Manual: Chapter 5. Monitoring Wells must be constructed according to Section 920.170 of the Illinois Water Well Construction Code: http://www.ilga.gov/commission/jcar/admincode/077/07700920sections.html Contact the approved local health department prior to constructing a monitoring well within its jurisdiction. Permitting requirements for Individual Residential Wells and Irrigation Wells are found in R.61-44, Individual Construction details for a groundwater monitoring well. Submit a permit modification application within 90 days to begin a compliance monitoring program. Notify the EPA Regional Administrator of the SSI within seven days. wells, see R.121-8, Oil and Gas Exploration, Drilling, and Production; and for monitoring and remediation wells at hazardous waste sites, see R.61-79, Hazardous Waste Management Regulations. This chapter applies to all persons installing and abandoning groundwater monitoring wells and boreholes for purposes regulated by the department under ch. Groundwater Classification (620 - Subpart B), Releases from Solid Waste Management Units. The compliance period during which the GWPS applies and compliance monitoring must be continued. Wells are safe, dependable sources of water if sited wisely and built correctly. Compliance monitoring must be continued during this period. Another statistical test method approved by the EPA Regional Administrator. The concentration limits for each of the listed constituents based either on background levels, Clean Water Act Maximum Contaminant Levels (MCLs), or alternate concentration levels (ACLs) determined by the EPA Regional Administrator. Under this phase, facilities are monitoring to detect and characterize any releases of hazardous constituents into the uppermost aquifer. These documents represent EPA Headquarters interpretations of the RCRA regulations governing the management of solid and hazardous waste. Typically, these requirements are included in a sampling and analysis plan. Any hazardous constituents that have migrated beyond the point of compliance must also be remediated. A minimum annular space of two (2) inches shall be maintained between the borehole wall and the outside diameter of the monitoring well casing. TSDFs that manage hazardous waste in landfills, surface impoundments, land treatment units and some waste piles (referred to as “regulated units” in the regulations) are required to implement a groundwater monitoring program to detect the release of hazardous constituents to the underlying groundwater. The design and installation of permanent monitoring wells involves drilling into various types of geologic formations that exhibit varying subsurface conditions. The owner/operators also must submit a permit modification application to establish a corrective action program. For permitted TSDFs, a groundwater monitoring program consists of three phases: detection monitoring (40 CFR section 264.98), compliance monitoring (40 CFR section 264.99), and corrective action (40 CFR section 264.100). RCRA Online – Search letters, memoranda, publications and questions and answers issued by EPA's Office of Resource Conservation and Recovery (ORCR). The interim status groundwater monitoring requirements apply only to facilities with hazardous waste landfills, surface impoundments or land treatment units in operation prior to the hazardous waste rules’ effective date. Sanitary control easements. To achieve this, the owner/operator must either remove the hazardous constituents or treat them in place. When analyzing the samples, facility owner/operators may use one of the following five methods: Unless the owner/operator can demonstrate that detected SSI is due to a sampling, analysis or statistical analysis error or natural variation in the groundwater chemistry, the facility must switch to a compliance monitoring program. These samples are analyzed to determine if a statistically significant increase (SSI) in the levels of any of the monitored constituents has occurred. units similar to the units identified in Items 1 through 3 which are being addressed in the RCRA corrective action program. Illinois EPA is committed to the protection of groundwater in the State of Illinois and better management of the groundwater data submitted to measure a facility's impact on groundwaters of the State. Facilities where groundwater monitoring and reporting is required include: On the At a minimum, samples must be taken at least semi-annually. Designing and installing permanent monitoring wells in these geologic environments may require several different drilling methods and installation procedures. Regulations Governing Treatment, Storage and Disposal Facilities. As part of this modified permit, the EPA Regional Administrator specifies the GWPS for the facility. Handbook of Groundwater Protection and Cleanup Policies for Resource Conservation and Recovery Act (RCRA) Corrective Action - Designed to help TSDF owners/operators find and understand EPA’s policies concerning groundwater protection and cleanup. The GWPS establishes: During compliance monitoring, samples are taken at each well located at the point of compliance (four samples from each well) and compared to the GWPS. All data collected as part of a facility’s groundwater monitoring program must be maintained in the facility’s operating record. Samples taken from the point of compliance (i.e., the wells down-gradient of the waste management unit) are compared to the background samples taken from the up-gradient well(s). If any new constituents are found to have an SSI then they must also be added to the GWPS list of constituents. Regulations Governing Treatment, Storage and Disposal Facilities - Provides introductory information on the groundwater monitoring requirements for hazardous waste TSDFs. permitted non-hazardous and hazardous waste landfills; land-based hazardous waste units (such as surface impoundments); units undergoing RCRA closure where contamination has possibly migrated to the groundwater; and.
