The agency may separately review and approve, disapprove, or approve subject to conditions, significant components of a local land use program which relate or pertain to the entire territorial jurisdiction of a local government, if proposed by the local government and formally submitted by its legislative body. The agency shall approve such components if the agency determines that such criteria of subdivision two of this section as shall be relevant to each such component are met. Provided, however, that the separately approved components of a local land use program shall not be deemed an approved local land use program for the purposes of this section, section eight hundred eight or section eight hundred nine of this article, unless and until all of the components of the local land use program shall have been approved pursuant to the terms of this subdivision or subdivision four of this section. Each such component shall be reviewed and acted upon in accordance with the procedures and within the time periods specified in subdivision one of this section relative to review of local land use programs. 4. The agency may review and approve, disapprove, or approve subject to conditions, an industrial site plan review law or ordinance, whether or not submitted as a component of a local land use program, if proposed by a local government and formally submitted by its legislative body. The agency shall approve such law or ordinance if the agency determines that such criteria of subdivision two of this section as shall be relevant to industrial uses and to sawmills, chipping mills, pallet mills and similar wood using facilities are met. Such law or ordinance shall provide for the review of such uses and facilities pursuant to the criteria and procedures set forth in paragraph f of subdivision two of this section. Notwithstanding any general or special law to the contrary, such law or ordinance shall relate and pertain to not more than two particular sites totalling one hundred acres or less, identified by the local government after a comprehensive study of the entire area within its jurisdiction, as appropriate for industrial uses and wood using facilities; provided, however, that no such site shall be located in a resource management area and no such site may be located in a rural use area remote from existing hamlet areas, or along major travel corridors where a park atmosphere prevails. Upon approval, or approval subject to conditions by the agency, and upon valid enactment or adoption of such law or ordinance, the authority of the agency over such uses and facilities pursuant to sections eight hundred six and eight hundred nine of this article shall be vested in the local government, whether or not such uses are class A regional projects. Such laws or ordinances shall be reviewed and acted upon in accordance with the procedures and within the time periods specified in subdivision one of this section relative to review of local land use programs. Section eight hundred eight of this article shall govern the administration and enforcement of such laws or ordinances. 5. The agency may review and approve, disapprove or approve subject to conditions, a local land use program insofar as it relates or pertains to one or more land use areas within the territorial jurisdiction of the local government which in the aggregate is a significant geographical portion of the territorial jurisdiction of the local government, if proposed by the local government and formally submitted by its legislative body. The agency shall approve such program if the agency determines that all criteria of subdivision two of this section are met with respect to such geographical portion. If approved, or approved subject to conditions by the agency, such validly enacted or adopted program, insofar as it pertains to such geographical portion, shall be deemed an approved local land use program with respect to such geographical portion in accordance with the terms and conditions of such approval, for the purposes of this section, section eight hundred eight and section eight hundred nine of this article. Provided, that nothing contained in this subdivision shall supercede or be construed in derogation of the provisions and requirements of the town law and village law otherwise applicable to the valid enactment or adoption of such program. The program, insofar as it pertains to such geographical portion, shall be reviewed and acted upon in accordance with the procedures and within the time periods specified in subdivision one of this section relative to review of local land use programs. 6. The agency shall, in its review of local land use programs, consult with appropriate public agencies, and shall provide opportunity for the Adirondack park local government review board and the appropriate county and regional planning agencies to review and comment on such programs under review. 7. The agency shall encourage and assist local governments in the preparation of local land use programs, including the provision of data, technical assistance and model provisions. Such model provisions shall be made available by the agency as soon as possible after the effective date of the adoption of the land use and development plan.
