Part 1001 - Content Of An Application
Section 1001.21 - Exhibit 21: geology, seismology and soils

Current through Register Vol. 46, No. 12, March 20, 2024

Exhibit 21 shall contain:

A study of the geology, seismology, and soils impacts of the facility consisting of the identification and mapping of existing conditions, an impact analysis, and proposed impact avoidance and mitigation measures, including:

(a) a map delineating existing slopes (0-3 percent, 3-8 percent, 8-15 percent, 15-25 percent, 25-35 percent, 35 percent and over) on and within the drainage area potentially influenced by the facility site and interconnections;

(b) a proposed site plan showing existing and proposed contours at two-foot intervals, for the facility site and interconnections, at a scale sufficient to show all proposed buildings, structures, paved and vegetative areas, and construction areas;

(c) a description and preliminary calculation of the quantity of cut and fill necessary to construct the facility, including separate calculations for topsoil, sub-soil and rock, and including a plan to identify the presence of invasive species in spoil material and to prevent the introduction and/or spread of invasive species by the transport of fill material to or from the site of the facility or interconnections;

(d) a description and preliminary calculation of the amount of fill, gravel, asphalt, and surface treatment material to be brought in to the facility site and interconnections;

(e) a description and preliminary calculation of the proposed type and amount of cut material or spoil to be removed from the facility site and interconnections;

(f) a description of excavation techniques to be employed;

(g) a delineation of temporary cut or fill storage areas to be employed;

(h) a description of the characteristics and suitability for construction purposes of the material excavated for the facility and of the deposits found at foundation level, including factors such as soil corrosivity, bedrock competence, and subsurface hydrologic characteristics;

(i) a preliminary plan describing all blasting operations including location, minimum blasting contractor qualifications, hours of blasting operations, estimates of amounts of rock to be blasted, warning measures, measures to ensure safe transportation, storage and handling of explosives, use of blasting mats, conduct of a pre-blasting condition survey of nearby buildings and improvements, and coordination with local safety officials;

(j) an assessment of potential impacts of blasting to environmental features, above-ground structures and below-ground structures such as pipelines and wells;

(k) an identification and evaluation of reasonable mitigation measures regarding blasting impacts, including the use of alternative technologies and/or location of structures, and including a plan for securing compensation for damages that may occur due to blasting;

(l) a description of the regional geology, tectonic setting and seismology of the facility vicinity.

(m) an analysis of the expected impacts of construction and operation of the facility with respect to regional geology, if such can be determined;

(n) an analysis of the impacts of typical seismic activity experienced in the facility area based on current seismic hazards maps, on the location and operation of the facility identifying potential receptors in the event of failure, and if the facility is proposed to be located near a young fault or a fault that has had displacement in Holocene time, demonstration of a suitable setback from such fault;

(o) a map delineating soil types on the facility and interconnections sites;

(p) a description of the characteristics and suitability for construction purposes of each soil type identified above, including a description of the soil structure, texture, percentage of organic matter, and recharge/infiltration capacity of each soil type and a discussion of any de-watering that may be necessary during construction and whether the facility shall contain any facilities below grade that would require continuous de-watering;

(q) maps, figures, and analyses delineating depth to bedrock and underlying bedrock types, including vertical profiles showing soils, bedrock, water table, seasonal high groundwater, and typical foundation depths on the facility site, and any area to be disturbed for roadways to be constructed and all off-site interconnections required to serve the facility, including an evaluation for potential impacts due to facility construction and operation, including any on-site wastewater disposal system, based on information to be obtained from available published maps and scientific literature, review of technical studies conducted on and in the vicinity of the facility, and on-site field observations, test pits and/or borings as available;

(r) an evaluation to determine suitable building and equipment foundations, including:

(1) a preliminary engineering assessment to determine the types and locations of foundations to be employed. The assessment shall investigate the suitability of such foundation types as spread footings, caissons, or piles, including a statement that all such techniques conform to applicable building codes or industry standards;

(2) if piles are to be used, a description and preliminary calculation of the number and length of piles to be driven, the daily and overall total number of hours of pile driving work to be undertaken to construct the facility, and an assessment of pile driving impacts on surrounding properties and structures due to vibration; and

(3) identification of mitigation measures regarding pile driving impacts, if applicable, including a plan for securing compensation for damages that may occur due to pile driving; and

(s) an evaluation of the vulnerability of the facility site and the operation of the facility to an earthquake event and a tsunami event.
