(1) The legislature finds that the construction and operation of large-scale metals mining and milling facilities may create new job opportunities and enhance local tax revenues. However, the legislature also finds that such operations may also result in new demands on public facilities owned and operated by local government entities, such as public streets and roads; publicly owned parks, open space, and recreation facilities; school facilities; and fire protection facilities in jurisdictions that are not part of a fire district. It is important for these economic impacts to be identified as part of any proposal for a large-scale metals mining and milling operation. It is then appropriate for the county legislative authority to balance expected revenues, including revenues derived from taxes paid by the owner of such an operation, and costs associated with the operation to determine to what degree any new costs require mitigation by the metals mining applicant.

(2) An applicant for a large-scale metals mining and milling operation regulated under this chapter must submit to the relevant county legislative authority an impact analysis describing the economic impact of the proposed mining operation on local governmental units. For the purposes of this section, a metals mining operation is large-scale if, in the construction or operation of the mine and the associated milling facility, the applicant and contractors at the site employ more than thirty-five persons during any consecutive six-month period. The relevant county is the county in which the mine and mill are to be sited, unless the economic impacts to local governmental units are projected to substantially affect more than one county. In that case, the impact plan must be submitted to the legislative authority of all affected counties. Local governmental units include counties, cities, towns, school districts, and special purpose districts.

(3) The economic impact analysis shall include at least the following information:

(a) A timetable for development of the mining operation, including the opening date of the operation and the estimated closing date;

(b) The estimated number of persons coming into the impacted area as a result of the development of the mining operation;

(c) An estimate of the increased capital and operating costs to local governmental units for providing services necessary as a result of the development of the mining operation; and

(d) An estimate of the increased tax or other revenues accruing to local governmental units as a result of development of the mining and milling operation.

(4) The county legislative authority of a county planning under chapter 36.70A RCW may assess impact fees under chapter 82.02 RCW to address economic impacts associated with development of the mining operation. The county legislative authority shall hold at least one public hearing on the economic impact analysis and any proposed mitigation measures.

(5) The county legislative authority of a county which is not planning under chapter 36.70A RCW may negotiate with the applicant on a strategy to address economic impacts associated with development of the mining operation. The county legislative authority shall hold at least one public hearing on the economic impact analysis and any proposed mitigation measures.

(6) The county legislative authority must approve or disapprove the impact analysis and any associated proposals from the applicant to address economic impacts to local governmental units resulting from development of the mining operation. If the applicant does not submit an adequate impact analysis to the relevant county legislative authority or if the county legislative authority does not find the applicant's proposals to be acceptable because of their failure to adequately mitigate adverse economic impacts, the county legislative authority shall refuse to issue any permits under its jurisdiction necessary for the construction or operation of the mine and associated mill.

(7) The requirements established in this section apply to metals mining operations under construction or constructed after April 1, 1994.

(8) The provisions of chapter 82.02 RCW shall apply to new mining and milling operations.
