PROPOSED STIPULATION NO. 8: SOILS, GEOLOGY AND SEISMOLOGY
The Application to be submitted will include a study of the soils, geology, floodplain and seismology in the Project area. The components of the evaluation will include identification and mapping of existing conditions, impact analysis, and proposed mitigation measures.

2. Regarding soils, geology, construction techniques, seismology, and flood hazards, the Study will include: SOILS
(a) A map delineating soil types, thickness, and depth to bedrock on the Project site and interconnectionst;
(b) A description of the characteristics and suitability for construction purposes of each soil type identified above, including a description of the recharge/infiltration capacity of each soil type and a discussion of any dewatering and disposal of excavation water that may be necessary during construction and whether the Project will contain any facilities below grade that would require continuous dewatering;
(c) A proposed site plan showing existing and proposed contours at 2-foot intervals on the Project site and interconnections at a scale sufficient to show all the proposed buildings, structures, paved, vegetative, and construction areas;
(d) A description of the contamination existing on the Project site and the remediation proposed by the Applicant.
GEOLOGY
(e) A map delineating underlying bedrock types on the Project site and interconnections, including an evaluation for potential impacts due to Project blasting, construction and operation, 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 Project, and on-site field observations, test pits and/or borings;
(f) A proposed site plan showing existing and proposed contours at two-foot intervals, for the Project site and interconnections, at a scale sufficient to show all proposed buildings, structures, paved and vegetated areas, and construction areas;
(g) A description and preliminary calculation of the quantity of cut to be removed from the Project site and interconnections, and fill material to be brought to the Project site and interconnections; including separate calculations for topsoil, sub-soil, fill, and rock as appropriate;
(h) A description of excavation techniques to be employed; and
(i) A delineation of any temporary cut or fill storage areas to be employed.
BLASTING
(j) A preliminary plan describing all blasting operations, if any, including location, blasting contractor qualifications, charge sizes and limits, quantity of discrete blasts, 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, a plan for a pre-blasting videotape condition survey of nearby buildings and improvements, and coordination with local safety officials;
(k) An assessment of potential impacts of blasting to environmental features, above-ground structures and below-ground facilities such as pipelines;
(l) 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;
SEISMOLOGY
(m) A description of the regional geology, tectonic setting and seismology of the Project vicinity;
(n) An identification of any potential impacts of geology and seismology on the Project.
FOUNDATIONS
An evaluation to determine suitable building and equipment foundations will be conducted. The evaluation will include:
(o) An engineering assessment to determine the types and locations of foundations to be employed. The assessment will investigate the suitability of such foundation types as spread footings, caissons, and piles.
(p) Identification of mitigation measures regarding pile-driving impacts if applicable.
STEAM INTERCONNECTION
An evaluation to determine the preferred and alternative construction methods for steam interconnection construction, including:
(q) A preliminary alternatives evaluation, to include directional drilling, tunnel boring, and use of existing infrastructure.
(r) The subsurface geology under the East River will be presented on the basis of available literature.
(s) A conceptual work plan, with descriptions of steam interconnection requirements, equipment to be used, impacts to bedrock geology, and contingency plans associated with direction drilling or tunnel boring.
FLOOD PLAIN
A floodplain evaluation will be conducted which includes:
(t) The preparation of a map indicating the location and type of flood plain found near the Project site.
(u) A consideration and discussion of the criteria of New York Coastal Management Program, Policies 11-18, pertaining to Flooding and Erosion Hazards; and
(v) An evaluation of potential flood plain hazards associated with the Project and mitigation measures, if any.
