3. The remedial action work plan Remedial Action Plan Report shall propose the activities, schedule, any permits required to initiate and complete the remediation and specific design plans for implementing remediation that will achieve the remediation levels specified in the risk assessment. Control or elimination of continuing onsite source or sources of releases to the environment shall be discussed. Land use controls should be discussed as appropriate. If no remedial action is necessary, the Remedial Action Plan shall discuss the reasoning for no action. When remedial activities have occurred prior to enrolling in the Voluntary Remediation Program, this information shall be included in the Site Characterization Report. The Remedial Action Plan Report shall describe the remedial activities that occurred, to include as applicable: how releases (or sources) have been eliminated or controlled; the remediation system or systems installed; site restrictions imposed; permits required; and how remediation levels have been achieved.

4. Demonstration of completion. A Demonstration of Completion Report is required whenever remedial action has occurred as part of participation in the Voluntary Remediation Program. The Demonstration of Completion Report shall include: a detailed summary of the performance of the remediation implemented at the site, the total cost of the remediation, and confirmational sampling results demonstrating that the established site-specific remedial objectives have been achieved, or that other criteria for completion of remediation have been satisfied. As part of the demonstration of completion, the participant shall certify compliance with applicable regulations pertaining to activities performed at the site pursuant to this chapter.

a. The demonstration of completion should, when applicable, include a detailed summary of the performance of the remediation implemented at the site, the total cost of the remediation, and confirmational sampling results demonstrating that the established site-specific remedial objectives have been achieved, or that other criteria for completion of remediation have been satisfied. If the participant elected to remit the statutory maximum registration fee and is not seeking a refund of any portion of the registration fee, the total cost of remediation need not be provided.

b. As part of the demonstration of completion, the participant shall certify compliance with applicable regulations pertaining to activities performed at the site pursuant to this chapter.

5. The participant shall provide documentation Documentation of public notice is required to demonstrate that public notice has been provided in accordance with 9VAC20-160-120. Such documentation shall include copies of comments received during the public comment period, all acknowledgements of receipt of comments, as well as the participant's responses to comments, if any are made.

B. It is the participant's responsibility to ensure that the investigation and remediation activities (e.g., waste management and disposal, erosion and sedimentation controls, air emission controls, and activities that impact wetlands and other sensitive ecological habitats) comply with all applicable federal, state, and local laws and regulations and any appropriate regulations that are not required by state or federal law but are necessary to ensure that the activities do not result in a further release of contaminants to the environment and are protective of human health and the environment.

C. All work, to include sampling and analysis, shall be performed in accordance with Test Methods for Evaluating Solid Waste, USEPA SW-846, revised April 1998 March 2009, or other media specific methods approved by the department and completed using appropriate quality assurance/quality control protocols. All analyses shall be performed by laboratories certified by the Virginia Environmental Laboratory Accreditation Program (VELAP). Laboratory certificates of analysis shall be included with applicable reports.

D. Until certificate issuance, all participants shall submit an annual report to the department containing a brief summary of any actions ongoing or completed as well as any planned future actions for the next reporting period. This report shall be submitted by July 1 using the "VRP Site Status Reporting Form."

9VAC20-160-90

9VAC20-160-90. Remediation levels.

A. The participant, with the concurrence of the department, shall consider impacts to human health and the environment in establishing remediation levels.

B. Remediation levels shall be based upon a risk assessment of the site and surrounding areas that may be impacted, reflecting the current and future use scenarios.

1. A site shall be deemed to have met the requirements for unrestricted use if the remediation levels, based on either background or standard residential exposure factors, have been attained throughout the site and in all media. Attainment of these levels will allow the site to be given an unrestricted use classification. No remediation techniques or land use controls that require ongoing management may be employed to achieve this classification.

2. For sites that do not achieve the unrestricted use classification, land use controls shall be applied. The restrictions imposed upon a site may be media-specific, may vary according to site-specific conditions, and may be applied to limit present and future use. All controls necessary to attain the restricted use classification shall be described in the certificate as provided in 9VAC20-160-110. Land use controls approved by the department for use at the site are considered remediation.

C. B. Remediation levels based on human health shall be developed after appropriate site characterization data have been gathered as provided in 9VAC20-160-70. Remediation levels may be derived from the three-tiered approach provided in this subsection. Any tier or combination of tiers may be applied to establish remediation levels for contaminants present at a given site, with consideration of site use restrictions specified in subsection B of this section.

1. Under Tier I the participant shall collect appropriate samples from background and from the area of contamination for all media of concern remediation levels are based on media backgrounds levels. These background levels shall be determined from a portion of the property or a nearby property or other areas as approved by the department that have not been impacted  by the contaminants of concern.

a. Background levels shall be determined from a portion of the property or a nearby property that has not been impacted by the contaminants of concern.

b. The participant shall compare concentrations from the area of contamination against background concentrations. If the concentrations from the area of contamination exceed established background levels, the participant may consider Tier II or Tier III methodologies, as applicable. If concentrations are at or below background levels, no further assessment is necessary.

2. Tier II generic remediation levels are media-specific values, derived using unrestricted use default assumptions assuming that there will be no restrictions on the use of groundwater, surface water, and soil on the site. Use of Tier II shall be limited to the following:

a. Tier II generic groundwater remediation levels shall be based on the most beneficial use of groundwater. The most beneficial use of groundwater is for a potable water source, unless demonstrated otherwise by the participant and accepted by the department. Therefore, they shall be based on (i) federal Maximum Contaminant Levels (MCLs) or action levels for lead and copper as established by the Safe Drinking Water Act (42 USC § 300 (f)) and the National Primary Drinking Water Regulations (40 CFR Part 141) or, in the absence of a MCL, (ii) tap water values derived using the methodology provided in the EPA Region III Risk-Based Concentration Table current at the time of the assessment Regional Screening Level Table, Region III, VI, and IX, United States Environmental Protection Agency, December 2009, using an acceptable individual carcinogenic risk of 1 X 10-5 and an individual noncarcinogen hazard quotient of 0.1. For contaminants that do not have values available under clauses (i) or (ii) above, a remediation level shall be calculated using criteria set forth under Tier III remediation levels.

b. Soil Tier II soil remediation levels shall insure that migration of contaminants shall not cause the cleanup levels established for groundwater and surface water to be exceeded. Soil remediation levels shall be determined as the lower of either the ingestion or cross-media transfer values, according to the following:

(1) For ingestion, values derived using the methodology provided in the EPA Region III Risk-Based Concentration Table current at the time of assessment. Regional Screening Level Table, Region III, VI, and IX, United States Environmental Protection Agency, December 2009.

(a) For carcinogens, the soil ingestion concentration for each contaminant, reflecting an individual upper-bound lifetime cancer risk of 1 X 10-6 10-5.

(b) For noncarcinogens, 1/10 (i.e., Hazard Quotient = 0.1) 0.1 of the soil ingestion concentration, to account for multiple systemic toxicants at the site. For sites where there are fewer than 10 contaminants exceeding 1/10 0.1 of the soil ingestion concentration, the soil ingestion concentration may be divided by the number of contaminants such that the resulting hazard index does not exceed one 1.0.

(2) For cross-media transfer, values derived from the USEPA Soil Screening Guidance (OSWER, July 1996, Document 9355.4-23, EPA/540/R-96/018) and USEPA Supplemental Guidance for Developing Soil Screening Levels for Superfund Sites (OSWER, December 2002, Document 9355.4-24) shall be used as follows:

(a) The soil screening level for transfer to groundwater, with adjustment to a hazard quotient of 0.1 for noncarcinogens, if the value is not based on a MCL; or

(b) The soil screening level for transfer to air, with adjustment to a hazard quotient of 0.1 for noncarcinogens and a risk level of 1 X 10-5 for carcinogens, using default residential exposure assumptions.

(3) (c) For noncarcinogens, for sites where there are fewer than 10 contaminants exceeding 1/10 0.1 of the soil screening level, the soil screening level may be divided by the number of contaminants such that the resulting hazard index does not exceed one 1.0.

(4) (3) Values derived under 9VAC20-160-90 C 2 b (1) and (2) may be adjusted to allow for updates in approved toxicity factors as necessary.

c. At sites where ecological receptors are of concern and there are complete exposure pathways, the participant shall perform a screening level ecological evaluation to show that remediation levels developed under Tier II are also protective of ecological receptors of concern.

d. For unrestricted future use, where a contaminant of concern exists for which c. Tier II remediation levels for surface water quality standards shall be based on the Virginia Water Quality Standards (WQS) have been adopted as established by the State Water Control Board for a specific use, the participant shall demonstrate that concentrations in other media will not result in concentrations that exceed the WQS in adjacent surface water bodies. (9VAC25-260), according to the following:

(1) The chronic aquatic life criteria shall be compared to the appropriate human health criteria and the lower of the two values selected as the Tier II remediation level.

(2) For contaminants that do not have a Virginia WQS, the federal Water Quality Criteria (WQC) may be used if available. The chronic federal criterion continuous concentration (CCC) for aquatic life shall be compared to the appropriate human health based criteria and the lower of the two values selected as the Tier II remediation level.

(3) If neither a Virginia WQS nor a federal WQC is available for a particular contaminant detected in surface water, the participant should perform a literature search to determine if alternative values are available. If alternative values are not available, the detected contaminants shall be evaluated through a site-specific risk assessment.

3. Tier III remediation levels are based upon a site-specific risk assessment considering site-specific assumptions about current and potential exposure scenarios for the population or populations of concern, including ecological receptors, and characteristics of the affected media and can be based upon a site-specific risk assessment. Land-use controls can be considered.

a. In developing Tier III remediation levels, and unless the participant proposes other guidance that is acceptable to the department, the participant shall use, for all media and exposure routes, the methodology specified in Risk Assessment Guidance for Superfund, Volume 1, Human Health Evaluation Manual (Part A), Interim Final, USEPA, December 1989 (EPA/540/1-89/002) and (Part B, Development of Preliminary Remediation Goals) Interim, USEPA, December 1991 (Publication 9285.7-01B) with modifications as appropriate to allow for site-specific conditions. The participant may use other methodologies approved by the department.

b. For a site with carcinogenic contaminants, the remediation goal for individual carcinogenic contaminants shall be an incremental upper-bound lifetime cancer risk of 1 X 10-6 10-5. The remediation levels for the site shall not result in an incremental upper-bound lifetime cancer risk exceeding 1 X 10-4considering multiple contaminants and multiple exposure pathways, unless the use of a MCL for groundwater that has been promulgated under 42 USC § 300g-1 of the Safe Drinking Water Act and the National Primary Drinking Water Regulations (40 CFR Part 141) results in a cumulative risk greater than 1 X 10-4.

c. For noncarcinogens, the hazard index shall not exceed a combined value of 1.0.

d. In setting remediation levels, the department may consider risk assessment methodologies approved by another regulatory agency and current at the time of the Voluntary Remediation Program site characterization.

e. Groundwater cleanup levels shall be based on the most beneficial use of the groundwater. The most beneficial use of the groundwater is for a potable water source, unless demonstrated otherwise by the participant and approved by the department.

f. For sites where a screening level ecological evaluation has shown that there is a potential for ecological risks, the participant shall perform an ecological risk assessment to show that remediation levels developed under Tier III are also protective of ecological receptors of concern. If the Tier III remediation levels developed for human health are not protective of ecological receptors of concern, the remediation levels shall be adjusted accordingly.

C. The participant shall determine if ecological receptors are present at the site or in the vicinity of the site and if they are impacted by releases from the site.

1. At sites where ecological receptors are of concern and there are complete exposure pathways, the participant shall perform a screening level ecological evaluation to show that remediation levels developed under the three-tiered approach described in this section are also protective of such ecological receptors.

2. For sites where a screening level ecological evaluation has shown that there is a potential for ecological risks, the participant shall perform an ecological risk assessment to show that remediation levels developed under the three-tiered approach described in this section are also protective of ecological receptors. If the remediation levels developed for human health are not protective of ecological receptors, the remediation levels shall be adjusted accordingly.

A. The director department shall issue a certification of satisfactory completion of remediation when:

1. The participant has demonstrated that migration of contamination has been stabilized;

2. The participant has demonstrated that the site has met the applicable remediation levels and will continue to meet the applicable remediation levels in the future for both on site and off site receptors; and

3. All provisions of the approved remedial action plan as applicable have been completed;

4. All applicable requirements of the regulations have been completed; and

3. 5. The department concurs with accepts all work submitted, as set forth in 9VAC20-160-80 9VAC20-160-70.

C. A site shall be deemed to have met the requirements for unrestricted use if the remediation levels, based on either background or standard residential exposure factors, have been attained throughout the site and in all media. Attainment of these levels will allow the site to be given an unrestricted use classification. No remediation techniques or land use controls that require ongoing management may be employed to achieve this classification.

D. For sites that do not achieve the unrestricted use classification, land use controls may be proffered in order to develop remediation levels based on restricted use. The restrictions imposed upon a site may be media-specific, may vary according to site-specific conditions, and may be applied to limit present and future use. All controls necessary to attain the restricted use classification shall be described in the certificate as provided in this section. Land use controls accepted by the department for use at the site are considered remediation for the purpose of this chapter.

C. E. If a use restriction is specified in the certificate, such restriction must be attached to the deed to the property with an explanation for the restriction, subject to concurrence by the director, and shall the participant shall cause the certificate to be recorded by the participant with among the land records for the site in the office of the clerk of the circuit court for the jurisdiction in which the site is located within 90 days of execution of the certificate by the department, unless specified in the certificate. The participant may also record the certificate itself. If the certificate does not include any use restriction, recordation of the certificate is at the option of the participant. The immunity accorded by the certification shall apply to the participant and shall run with the land identified as the site.

D. F. The immunity granted by issuance of the certificate shall be limited to site conditions at the time of issuance as those conditions are described in the Voluntary Remediation Report. The immunity is further conditioned upon satisfactory performance by the participant of all obligations required by the director department under the program and upon the veracity, accuracy, and completeness of the information submitted to the director department by the participant relating to the site. Specific limitations of the certificate shall be enumerated in the certificate. The immunity granted by the certificate shall be dependent upon the identification of the nature and extent of contamination as presented in the report.

E. G. The certificate shall specify the conditions for which immunity is being accorded, including, but not limited to:

1. A summary of the information that was considered;

2. Any restrictions on future use;

3. Any local land use controls on surrounding properties that were taken into account; and

4. Any required proffered land use controls including:; and

a. Engineering controls and their maintenance; and

b. Institutional controls.

5. Any post-certificate monitoring.

F. H. The certificate may be revoked by the director department at any time in the event that conditions at the site, unknown at the time of issuance of the certificate, pose a risk to human health or the environment or in the event that the certificate was based on information that was false, inaccurate, or misleading. The certificate may also be revoked for the failure to meet or maintain the conditions of the certificate. Any and all claims may be pursued by the Commonwealth for liability for failure to meet a requirement of the program, criminal liability, or liability arising from future activities at the site that may cause contamination by pollutants. By issuance of the certificate the director department does not waive sovereign immunity. Failure to implement and maintain land use controls may result in revocation of the certificate.

G. I. The certificate is not and shall not be interpreted to be a permit or a modification of an existing permit or administrative order issued pursuant to state law, nor shall it in any way relieve the participant of its obligation to comply with any other federal or state law, regulation or administrative order.
