1. Where proven technology is available and the economic impact is reasonable, pursuant to rules and regulations promulgated by the commission, the hazardous waste management commission shall encourage that every effort is made to effectively treat, recycle, detoxify, incinerate or otherwise treat hazardous waste to be disposed of in the state of Missouri in order that such wastes are not disposed of in a manner which is hazardous to the public health and the environment. Where proven technology is available with respect to a specific hazardous waste and the economic impact is reasonable, pursuant to rules and regulations promulgated by the commission, the hazardous waste management commission shall direct that disposal of the specific hazardous wastes using land filling as the primary method is prohibited.
2. The hazardous waste management commission shall, by rules and regulations, categorize hazardous waste by taking into account toxicity, persistence and degradability in nature, potential for accumulation in tissue, and other related factors such as flammability, corrosiveness and other hazardous characteristics. The commission shall by rules and regulations further establish within each category the wastes which may or may not be disposed of through alternative hazardous waste management technologies including, but not limited to, treatment facilities, incinerators, landfills, landfarms, storage facilities, surface impoundments, recycling, reuse and reduction. The commission shall specify, by rule and regulation, the frequency of inspection for each method of hazardous waste management and for the different waste categories at hazardous waste management sites. The inspection may be daily when the hazardous waste management commission deems it necessary. The hazardous waste management commission shall specify, by rule, fees to be paid to the department by owners or operators of hazardous waste facilities who have obtained, or are required to obtain, a hazardous waste facility permit and who accept, on a commercial basis for remuneration, hazardous waste from off-site sources, but not including wastes generated by the same person at other sites located in Missouri or within a metropolitan statistical area located partially in Missouri and owned or operated by the same person and transferred to the hazardous waste facility, for treatment, storage or disposal, for inspections conducted by the department to determine compliance with sections 260.350 to 260.430 and the regulations promulgated thereunder. Funds derived from these inspection fees shall be used for the purpose of funding the inspection of hazardous waste facilities, as specified in subsection 3 of section 260.391 . Such fees shall not exceed twelve thousand dollars per year per facility and the commission shall establish a graduated fee scale based on the volume of hazardous waste accepted with reduced fees for facilities accepting smaller volumes of hazardous waste. The department shall furnish, upon request, to the person, firm or corporation operating the hazardous waste facility a complete, full and detailed accounting of the cost of the department's inspections of the facility for the twelve-month period immediately preceding the request within forty-five days after receipt of the request. Failure to provide the accounting within forty-five days shall require the department to refund the inspection fee paid during the twelve-month-time period.
3. In addition to any other powers vested in it by law, the commission shall have the following powers:
(1) From time to time adopt, amend or repeal, after due notice and public hearing, standards, rules and regulations to implement, enforce and carry out the provisions of sections 260.350 to 260.430 and any required of this state by any federal hazardous waste management act and as the commission may deem necessary to provide for the safe management of hazardous wastes to protect the health of humans and the environment. In implementing this subsection, the commission shall consider the variations within this state in climate, geology, population density, quantities and types of hazardous wastes generated, availability of hazardous waste facilities and such other factors as may be relevant to the safe management of hazardous wastes. Within two years after September 28, 1977, the commission shall adopt rules and regulations including the following:
(a) Rules and regulations establishing criteria and a listing for the determination of whether any waste or combination of wastes is hazardous for the purposes of sections 260.350 to 260.430 , taking into account toxicity, persistence and degradability in nature, potential for accumulation in tissue, and other related factors such as flammability, corrosiveness and other hazardous characteristics;
(b) Rules and regulations for the storage, treatment and disposal of hazardous wastes;
(c) Rules and regulations for the transportation, containerization and labeling of hazardous wastes, which shall be consistent with those issued by the Missouri public service commission;
(d) Rules and regulations establishing standards for the issuance, modification, suspension, revocation or denial of such licenses and permits as are consistent with the purposes of sections 260.350 to 260.430 ;
(e) Rules and regulations establishing standards and procedures for the safe operation and maintenance of hazardous waste facilities in order to protect the health of humans and other living organisms;
(f) Rules and regulations listing those wastes or combinations of wastes, for which criteria have been established under paragraph (a) of this subdivision and which are not compatible and which may not be stored or disposed of together;
(g) Rules and regulations establishing procedures and requirements for the reporting of the generation, storage, transportation, treatment or disposal of hazardous wastes;
(2) Adopt and publish, after notice as required by the provisions of chapter 536 pertaining to administrative rulemaking, and public hearing, a state hazardous waste management plan to provide for the safe and effective management of hazardous wastes within this state. This plan shall be adopted within two years after September 28, 1977, and revised at least once every five years thereafter;
(3) Hold hearings, issue notices of hearings and subpoenas requiring the attendance of witnesses and the production of evidence, administer oaths and take testimony as the commission deems necessary to accomplish the purposes of sections 260.350 to 260.430 or as required by any federal hazardous waste management act. Unless otherwise specified in sections 260.350 to 260.430 , any of these powers may be exercised on behalf of the commission by any members thereof or a hearing officer designated by it;
(4) Grant individual variances in accordance with the provisions of sections 260.350 to 260.430 ;
(5) Make such orders as are necessary to implement, enforce and effectuate the powers, duties and purposes of sections 260.350 to 260.430 .
4. No rule or portion of a rule promulgated under the authority of sections 260.350 to 260.480 and sections 260.565 to 260.575 shall become effective unless it has been promulgated pursuant to the provisions of section 536.024 .
5. To the extent there is a conflict concerning authority for risk-based remediation rules between this section and section 644.143 or subdivision (8) of section 644.026 , this section shall prevail.
