    RULE ANALYSIS

    Purpose of the rule or reason for the change:

    The rule is being updated to reflect current references and additions to EPA Drinking Water standards. EPA Drinking Water standards are incorporated into the ground water quality standards. The rule is also being modified to allow for a more reasonable allowance for natural variations in background water quality in an effort to reduce false positives.

     

    Summary of the rule or change:

    The rule changes include three primary changes: 1) updating Ground Water Quality Standards Table (Table 1), to reflect changes and additions to Federal Maximum Contamination Levels and Maximum Residual Disinfection Levels under EPA Drinking Water regulations; 2) updated definitions and references throughout the ground water rules; and 3) adjustments to protection levels to reflect a more reasonable representation of natural background variation in groundwater and reduce the occurrence of false positives.

     

    State statutory or constitutional authorization for this rule:

    Section 19-4-104

     

    Anticipated cost or savings to:

    the state budget:

    No additional costs or savings are anticipated. The changes in protection levels will allow State staff to minimize time spent on erroneous out of compliance issues.

     

    local governments:

    The proposed changes do not directly affect local governments. No additional costs or savings are anticipated.

     

    other persons:

    The proposed changes in protection levels will reduce unnecessary accelerated monitoring and analysis costs for some permittees.

     

    Compliance costs for affected persons:

    No additional compliance costs are anticipated as a result of the proposed amendments. The proposed changes in protection levels will reduce unnecessary accelerated monitoring and analysis costs for some permittees, unwarranted expenditure of Division resources, and undue public concern.

     

    Comments by the department head on the fiscal impact the rule may have on businesses:

    The proposed changes in protection levels will reduce unnecessary accelerated monitoring and analysis costs for some permittees.

    R. All applications for a groundwater discharge permit must be performed under the direction, and bear the seal, of a professional engineer or professional geologist.

    S. A closure and post closure management plan demonstrating measures to prevent ground water contamination during the closure and post closure phases of an operation.

    6.4 ISSUANCE OF DISCHARGE PERMIT

    A. The Executive Secretary may issue a ground water discharge permit for a new facility if the Executive Secretary determines, after reviewing the information provided under R317-6-6.3, that:

    1. the applicant demonstrates that the applicable class TDS limits, ground water quality standards protection levels, and permit limits established under R317-6-6.4E will be met;

    2. the monitoring plan, sampling and reporting requirements are adequate to determine compliance with applicable requirements;

    3. the applicant is using best available technology to minimize the discharge of any pollutant; and

    4. there is no impairment of present and future beneficial uses of the ground water.

    B. The Board may approve an alternate concentration limit for a new facility if:

    1. The applicant submits a petition for an alternate concentration limit showing the extent to which the discharge will exceed the applicable class TDS limits, ground water standards or applicable protection levels and demonstrates that:

    a. the facility is to be located in an area of Class III ground water;

    b. the discharge plan incorporates the use of best available technology;

    c. the alternate concentration limit is justified based on substantial overriding social and economic benefits; and,

    d. the discharge would pose no threat to human health and the environment.

    2. One or more public hearings have been held by the Board in nearby communities to solicit comment.

    C. The Executive Secretary may issue a ground water discharge permit for an existing facility provided:

    1. the applicant demonstrates that the applicable class TDS limits, ground water quality standards and protection levels will be met;

    2. the monitoring plan, sampling and reporting requirements are adequate to determine compliance with applicable requirements;

    3. the applicant utilizes treatment and discharge minimization technology commensurate with plant process design capability and similar or equivalent to that utilized by facilities that produce similar products or services with similar production process technology; and,

    4. there is no current or anticipated impairment of present and future beneficial uses of the ground water.

    D. The Board may approve an alternate concentration limit for a pollutant in ground water at an existing facility or facility permitted by rule under R317-6-6.2 if the applicant for a ground water discharge permit shows the extent the discharge exceeds the applicable class TDS limits, ground water quality standards and applicable protection levels that correspond to the otherwise applicable ground water quality standards and demonstrates that:

    1. steps are being taken to correct the source of contamination, including a program and timetable for completion;

    2. the pollution poses no threat to human health and the environment; and

    3. the alternate concentration limit is justified based on overriding social and economic benefits.

    E. An alternate concentration limit, once adopted by the Board under R317-6-6.4B or R317-6-6.4D, shall be the pertinent permit limit.

    F. A facility permitted under this provision shall meet applicable class TDS limits, ground water quality standards, protection levels and permit limits.

    G. The Board may modify a permit for a new facility to reflect standards adopted as part of corrective action.

    6.16 OUT-OF-COMPLIANCE STATUS

    A. Accelerated Monitoring for Probable Out-of-Compliance Status

    If the [concentration]value of a single analysis of a pollutant concentration in any compliance monitoring sample exceeds an applicable permit limit, the facility shall:

    1. Notify the Executive Secretary in writing within 30 days of receipt of data;

    2. [Initiate]Immediately initiate monthly sampling if the value exceeds both the background concentration of the pollutant by two standard deviations and an applicable permit limit, unless the Executive Secretary determines that other periodic sampling is appropriate, for a period of two months or until the compliance status of the facility can be determined.

    B. Violation of Permit Limits

    Out-of-compliance status exists when:

    1. The value for two consecutive samples from a compliance monitoring point exceeds:

    a. one or more permit limits; and

    b. the [mean ground water pollutant]background concentration for that pollutant by two standard deviations (the standard deviation and background (mean)[mean] being calculated using values for the ground water pollutant at that compliance monitoring point) unless the existing permit limit was derived from the background pollutant concentration plus two standard deviations; or

    2. the concentration value of any pollutant in two or more consecutive samples is statistically significantly higher than the applicable permit limit. The statistical significance shall be determined using the statistical methods described in Statistical Methods for Evaluating Ground Water Monitoring Data from Hazardous Waste Facilities, Vol. 53, No. 196 of the Federal Register, Oct. 11, 1988 and supplemental guidance in Guidance For Data Quality Assessment (EPA/600/R-96/084 January 1998).

    C. Failure to Maintain Best Available Technology Required by Permit

    1. Permittee to Provide Information

    In the event that the permittee fails to maintain best available technology or otherwise fails to meet best available technology standards as required by the permit, the permittee shall submit to the Executive Secretary a notification and description of the failure according to R317-6-6.13. Notification shall be given orally within 24 hours of the permittee's discovery of the failure of best available technology, and shall be followed up by written notification, including the information necessary to make a determination under R317-6-6.16.C.2, within five days of the permittee's discovery of the failure of best available technology.

    2. Executive Secretary

    The Executive Secretary shall use the information provided under R317-6-6.16.C.1 and any additional information provided by the permittee to determine whether to initiate a compliance action against the permittee for violation of permit conditions. The Executive Secretary shall not initiate a compliance action if the Executive Secretary determines that the permittee has met the standards for an affirmative defense, as specified in R317-6-6.16.C.3.

    3. Affirmative Defense

    In the event a compliance action is initiated against the permittee for violation of permit conditions relating to best available technology, the permittee may affirmatively defend against that action by demonstrating the following:

    a. The permittee submitted notification according to R317-6-6.13;

    b. The failure was not intentional or caused by the permittee's negligence, either in action or in failure to act;

    c. The permittee has taken adequate measures to meet permit conditions in a timely manner or has submitted to the Executive Secretary, for the Executive Secretary's approval, an adequate plan and schedule for meeting permit conditions; and

    d. The provisions of 19-5-107 have not been violated.
