(5) The effectiveness of the measures proposed by the applicant to avoid, minimize, or mitigate unreasonable adverse effects on historic sites and archaeological resources, and the extent to which such measures represent best practical measures.

(c) In determining whether a proposed energy facility will have an unreasonable adverse effect on air quality, the committee shall consider the determinations of the New Hampshire department of environmental services with respect to applications or permits identified in Site 301.03(d) and other relevant evidence submitted pursuant to Site 202.24.

(d) In determining whether a proposed energy facility will have an unreasonable adverse effect on water quality, the committee shall consider the determinations of the New Hampshire department of environmental services, the United States Army Corps of Engineers, and other state or federal agencies having permitting or other regulatory authority, under state or federal law, to regulate any aspect of the construction or operation of the proposed facility, with respect to applications and permits identified in Site 301.03(d), and other relevant evidence submitted pursuant to Site 202.24.

(e) In determining whether construction and operation of a proposed energy facility will have an unreasonable adverse effect on the natural environment, including wildlife species, rare plants, rare natural communities, and other exemplary natural communities, the committee shall consider:

(1) The significance of the affected resident and migratory fish and wildlife species, rare plants, rare natural communities, and other exemplary natural communities, including the size, prevalence, dispersal, migration, and viability of the populations in or using the area;

(2) The nature, extent, and duration of the potential effects on the affected resident and migratory fish and wildlife species, rare plants, rare natural communities, and other exemplary natural communities;

(3) The nature, extent, and duration of the potential fragmentation or other alteration of terrestrial or aquatic significant habitat resources or migration corridors;

(4) The analyses and recommendations, if any, of the department of fish and game, the natural heritage bureau, the United States Fish and Wildlife Service, and other agencies authorized to identify and manage significant wildlife species, rare plants, rare natural communities, and other exemplary natural communities;

(5) The effectiveness of measures undertaken or planned to avoid, minimize, or mitigate potential adverse effects on the affected wildlife species, rare plants, rare natural communities, and other exemplary natural communities, and the extent to which such measures represent best practical measures;

(6) The effectiveness of measures undertaken or planned to avoid, minimize, or mitigate potential adverse effects on terrestrial or aquatic significant habitat resources, and the extent to which such measures represent best practical measures; and

(7) Whether conditions should be included in the certificate for post-construction monitoring and reporting and for adaptive management to address potential adverse effects that cannot reliably be predicted at the time of application.

(f) In determining whether a proposed energy facility will have an unreasonable adverse effect on public health and safety, the committee shall:

(1) For all energy facilities, consider the information submitted pursuant to Site 301.08 and other relevant evidence submitted pursuant to Site 202.24, the potential adverse effects of construction and operation of the proposed facility on public health and safety, the effectiveness of measures undertaken or planned to avoid, minimize, or mitigate such potential adverse effects, and the extent to which such measures represent best practical measures;

(2) For wind energy systems, apply the following standards:

a. With respect to sound standards, the A-weighted equivalent sound levels produced by the applicant's energy facility during operations shall not exceed the greater of 45 dBA or 5 dBA above background levels, measured at the L-90 sound level, between the hours of 8:00 a.m. and 8:00 p.m. each day, and the greater of 40 dBA or 5 dBA above background levels, measured at the L-90 sound level, at all other times during each day, as measured using microphone placement at least 7.5 meters from any surface where reflections may influence measured sound pressure levels, on property that is used in whole or in part for permanent or temporary residential purposes, at a location between the nearest building on the property used for such purposes and the closest wind turbine; and

b. With respect to shadow flicker, the shadow flicker created by the applicant's energy facility during operations shall not occur more than 8 hours per year at or within any residence, learning space, workplace, health care setting, outdoor or indoor public gathering area, or other occupied building;

(3) For wind energy systems, consider the proximity and use of buildings, property lines, public roads, and overhead and underground energy infrastructure and energy transmission pipelines, the risks of ice throw, blade shear, tower collapse, and other potential adverse effects of facility operation, and the effectiveness of measures undertaken or planned to avoid, minimize, or mitigate such potential adverse effects, and the extent to which such measures represent best practical measures;

(4) For electric transmission lines, consider the proximity and use of buildings, property lines, and public roads, the risks of collapse of towers, poles, or other supporting structures, the potential impacts on public health and safety of electric and magnetic fields generated by the proposed facility, and the effectiveness of measures undertaken or planned to avoid, minimize, or mitigate such potential adverse effects, and the extent to which such measures represent best practical measures;

(5) For high pressure gas pipelines, apply the following standards:

a. With respect to sound standards for interstate pipelines, the noise attributable to any new compressor station, compression added to an existing station, or any modification, upgrade or update of an existing station, shall not exceed a day-night sound level (Ldn) of 55 dBA at any pre-existing noise-sensitive area, such as schools, hospitals, or residences, as provided in 18 CFR § 380.12(k), available as noted in Appendix B;

b. With respect to sound standards for intrastate pipelines, the noise attributable to any new compressor station, compression added to an existing station, or any modification, upgrade or update of an existing station, shall not exceed the standards set forth in (2)a., above, regarding wind energy systems;

c. With respect to vibration, compressor stations or modifications of existing compressor stations shall not result in a perceptible increase in vibration at any pre-existing noise-sensitive area, such as schools, hospitals, or residences, as provided in 18 CFR § 380.12(k), available as noted in Appendix B, or a level of 2.0 peak particle velocity, whichever is less;
