Groundwater Protection Act

Summary

ALEC’s model Groundwater Protection Act is designed to futher document and ensure the safety of America’s drinking water through the prevention, minimization, or mitigation of the movement of chemicals to drinking water supplies derived from ground water acquifers. Key components of the bill include: implementation of a state monitoring program, groundwater contamination assessments based on numerical standards, agricultural chemical management areas, and agricultural chemical management plans.

Model Policy

{Title, enacting clause, etc.}

Section 1. {Short Title.} This act shall be known and may be cited as the Groundwater Protection Act.

Section 2. {Legislative findings and declarations.}

The legislature finds and declares:

(A) That the highest and best use of groundwater is for drinking purposes, and therefore groundwater must be adequately protected through feasible prevention, minimization, and mitigation of such water supplies.

(B) That the general health and well being of the people requires that groundwaters used for drinking, including potential sources of drinking water, not only be properly protected but are safe for consumption, subject to reasonable regulation.

(C) That the current legislative authority provides insufficient administrative and regulatory options necessary to protect public health. Such protection can be achieved through minimizing exposure while providing a balanced approach that preserves the social, environmental, and economic benefits of agricultural chemicals for people.

(D) That the rapid increase in laboratory analytical capabilities has resulted in findings of chemicals in drinking water supplies derived from ground water aquifers.

(E) The ability to predict the potential appearance of chemicals in drinking water supplies is based upon certain physical characteristics and behavior in the environment and it is necessary to prevent, minimize, and mitigate the presence of chemicals in groundwater.

(F) That scientific procedures exist that permit the prediction of the potential for movement of chemicals through soils, and the likelihood, with a sufficient level of scientific probability, of their subsequent entry into drinking water supplies. The ability to prevent, minimize, or mitigate the movement of chemicals to groundwater by utilizing available predictive procedures must be supported by scientifically valid soil and groundwater monitoring programs.

(G) That the use of numerical, health-based standards for drinking water is a sound groundwater resource management approach. Numerical standards, in this act, will be used to initiate and provide management recommendations and requirements for groundwater protection programs that minimize, mitigate, and prevent the concentration of chemicals in drinking water supplies derived from groundwater aquifers. Such standards for chemicals should be based on the best available scientific data.

(H) That the purpose of this act is to protect public health by preventing, minimizing, or mitigating the movement of chemicals to drinking water supplies of this state. This will be accomplished through prediction, assessment with regard to the potential impact on public health, subsequent monitoring, and, if necessary, regulatory remediation of chemical presence in groundwater through a program of best management plans, agricultural chemical management plans, public education, and training.

Section 4. {Preliminary research.}

(A) Implementation of program. The Director of Agriculture, in consultation with the Director of the [cite appropriate state agency], shall develop and implement a program to determine, with a reasonable degree of scientific probability, the likelihood of chemicals entering sources of drinking water. In establishing this program, the Director shall:

(1) Review appropriate scientific references and data available to the Director regarding prediction criteria for chemicals used in this state that are either known to be present, or with a reasonable degree of scientific certainty may be present, in drinking water. In conduction with such review, the Director shall consider all relevant factors, including, but not limited to, currently available hydrological, geological, and meteorological data, areas of chemical use in this state while also considering local agricultural practices and habits.

(2) In cases where either references or data are not available to the Director, the Director shall consult with other state agencies or federal agencies and other viable resources that may have such information or may have access to such information. When available, the state agency shall provide the Director with either references or data summaries that will, to the extent possible, satisfy the need for the prediction criteria.

(B) Contamination assessment. Upon determination by the Director that sufficient information is available to satisfy the prediction criteria, the Director shall conduct, in consultation with the Director of the [cite appropriate state agency], an assessment at the likelihood for a chemical to enter sources of drinking water. In conducting such assessment, the Director shall utilize the predictive procedures that provide the highest degree of scientific certainty that are most appropriate for the State of (insert state) conditions of use.

(C) Monitoring program. For each chemical identified as likely to enter sources of drinking water, the Director, in cooperation with other appropriate agencies, shall establish and commence a monitoring program to assist in defining:

(1) Whether the chemical has entered a source of drinking water.

(2) Whether the chemical has a reasonable probability of entering a source of drinking water due to migration through soil and from point-source origination.

(3) Whether the level of the chemical in sources of drinking water or its rate of migration through soil is increasing or decreasing with respect to the numerical standards established herein.

(4) The reliability of the predictive procedure.

(5) Potential best management practices or plans for the chemical or chemicals in question.

Section 5. {Monitoring Program.}

(A) General parameters. The Director of the [cite appropriate state agency], in cooperation with the Director of Agriculture, shall conduct scientifically planned and accepted monitoring programs. The Director shall monitor those areas of the state which have been identified, using either predictive procedures, hydrologic evaluation or other information, as having reasonable likelihood that the appearance of a chemical will increase in frequency and concentration in sources of drinking water and is likely to exceed a duly adopted standard.

(B) Techniques and procedures. Those laboratories conducting analytical and monitoring studies shall utilize good laboratory practices (GLPs) and other scientifically accepted and certified analytical techniques and sampling procedures, hydrologic evaluation, or other information, as having a reasonable likelihood that the appearance of a chemical will increase in frequency and concentration in sources of drinking water and is likely to exceed a duly adopted standard.

(C) Design and scope. Prior to initiation of the monitoring program, the Director of the [cite appropriate state agency] shall consult with the Director of Agriculture and other appropriate agencies concerning the design and scope of monitoring requirements imposed in this section. The design and scope of the monitoring requirement should take into account the magnitude and frequency of the detection of the pesticide involved, pattern of pesticide use, soil types involved in detection, its use in vulnerable areas, physical and chemical properties of the pesticide, rainfall patterns, well construction if the pesticide was detected in a well, rates of degradation, reliability and analytical accuracy of the detection, and results of other sponsored monitoring. To the extent feasible, monitoring should be at representative geographical and hydrological areas associated with locations and conditions of concern as determined by the Director.

(D) Independent informational sources. The Director of the [cite appropriate state agency] may receive and evaluate information on similar monitoring programs from other interested persons including other state or federal agencies, or independent sources. Information received shall be evaluated based upon the standard procedures, protocols, and confirmatory procedures established under this act. Information found not to be in accord with standard procedures, protocols, and confirmatory procedures, including analyses, shall be deemed for information purposes only.

Section 6. {Establishment of numerical standards.}

(A) Methodology. Prior to initiating any monitoring required under subsection (C) of Section 4 of this act, the Director of Agriculture shall notify the Director of the [cite appropriate state agency] of those chemicals for which monitoring will be carried out. Within 90 days after sending such notice, the Director, if necessary, shall initiate a methodology pursuant to the state Administrative Procedures Act [cite code section] for the establishment of numerical standards for chemicals in drinking water supplies as follows:

(1) If a promulgated federal number exists for a chemical, that number shall be the standard.

(2) If no promulgated federal number has been established, but a non-promulgated federal number has been published, the non-promulgated federal number shall be the standard.

(3) If no promulgated or non-promulgated federal number exists, the Director shall petition the U.S. Environmental Protection Agency to establish a number as defined in Section 2 (G) of this act for the chemical of interest. If the Director determines that such number cannot be obtained within 30 days, the Director shall develop and adopt an interim numerical standard following the procedure specified in subsection (A) and (E) of this Section. The interim numerical standard shall be developed as specified in subsection (C) of this Section, and shall be used until a non-promulgated or promulgated federal number, as defined herein, has been established for that chemical.

(B) Subsequent federal numbers. Should a promulgated federal number be issued subsequent to the establishment of the interim numerical standard, the state shall adopt the new federal number as the standard.

(C) Interim standard. Notwithstanding paragraphs (1) and (2) of subsection (A) of this section, the Director, as an option, may adopt an interim standard different than the promulgated or non-promulgated federal number if there is significant new and relevant technical information that is scientifically valid and which was not considered when the original number was established. However, the Director must find, utilizing the methodology pursuant to this section of this act, and with reasonable scientific certainty, that the different interim standard is justified.

(1) In evaluating the evidence for establishing an interim standard different than a number as set forth in this act, the Director shall consider the extent to which the evidence was developed in accordance with scientifically valid protocols, procedure, and recommendations for conduct of the evidence. The Director shall also consider whether the evidence was subjected to peer review, resulted from more than one study, and is consistent with other credible medical or toxicological evidence.

(2) If the Director adopts an interim standard different form an existing promulgated or non-promulgated federal number, such interim numerical standards shall be established according to the methodology of this section of this act and shall be subject to judicial review.

(D) Reporting requirements. In adopting any standard pursuant to this section, the Director shall publish a document for distribution to interested persons, including affected registrants, at least 60 days prior to any hearing on a regulation establishing a standard. Such document shall describe the information and methodology used and the conclusions reached in proposing the standard.

(E) Interagency consultation. In the development of an interim numerical standard different from or in the absence of a promulgated or non-promulgated federal number, the Director of the [cite appropriate state agency] shall consult the U.S. Environmental Protection Agency’s Office of Drinking Water and Office of Pesticide Programs regarding the U.S. Environmental Protection Agency’s conclusion relative to available toxicological information on the chemical in question and on the methodology used by the U.S. Environment Protection Agency for establishing non-promulgated federal numbers as defined herein. The Director shall utilize this information to establish an interim numerical standard for drinking water in accordance with a due regulatory rule making process under the Administrative Procedures Act [cite code section] of the State. Any number utilized as an interim numerical standard for drinking water shall be subject to judicial review.

(F) Oncogen assessment. If the scientific data indicate oncogenic potential for a chemical, but the U.S. Environmental Protection Agency, under an oncogen assessment policy, has determined that a numerical risk assessment is not justified or inappropriate, or does not serve as the primary toxicological basis for regulation, the Director shall utilize the methodology prescribed in paragraph (C) of subsection (1) of this Section of this act, adopting the margin of safety used by the federal agency.

(G) Chemical standards. The standard for a chemical shall be based upon a 70 kilogram person drinking two liters of water per day.

Section 7. {Evaluation of monitoring results.}

(A) Data review. The Director of Agriculture, in consultation with the Director of the [cite appropriate state agency] and other appropriate agencies, shall conduct an evaluation of the results of the monitoring program carried out pursuant to Section 5 of this act to make the following determinations:

(1) Whether the actual presence of the chemical in sources of drinking water exceeds the standard established pursuant to Section 6 of this act and the geographical extent of the determined presence of the chemical in sources of drinking water; and

(2) Whether the data collected by monitoring, when reviewed by the Director, indicate a trend that the duly adopted standard will be exceeded. In determining such a trend, the Director shall take into consideration the percentage change in the concentration of chemicals determined at various sites over a reasonable period of time.

(B) Exceedence of standards. When the Director determines that a standard has been exceeded at a groundwater sampling point, or when trends as set forth in paragraph (2) of subsection (A) of this section indicate that the standards will be exceeded, the Director shall determine the significance and notify the registrants of the chemical and other affected persons of such determinations.

(C) Administrative and regulatory remedies. Upon determination by the Director that a standard has been exceeded or a high degree of scientific certainty that such a standard will be exceeded, the Director shall implement appropriate administrative or regulatory remedies, which may include best management practices, and taking all reasonable time estimates into account, under authority provided to prevent, mitigate, or minimize future impact of the chemical in sources of drinking water. Periodic evaluation of the monitoring of the effectiveness of any administrative or regulatory remedies shall be conducted by the Director to determine the necessity to revise, amend, or withdraw any such remedies.

(D) Management recommendations. Nothing in this act shall prevent the Director, in cooperation with the University Extension Service, other cooperating agencies, or interested parties from developing and promoting appropriate best management practice recommendations.

Section 8. {Agricultural chemical management areas.}

(A) Establishment of criteria. The Director shall, in consultation with appropriate agencies, registrants, and other interested parties, develop specific criteria necessary for identifying agricultural chemical management areas and adopt the criteria by rule.
