NTH’S VALUE ADDED
NTH maintains an experienced staff that has a thorough understanding of state and federal environmental regulations applicable to the power generation industry, as well as a strong working relationship with regulatory agencies. Our experience in environmental permitting includes several electric generating plants both operational and those currently under construction.
Environmental Permitting Services
Electric Generation Facilities
New generation facilities are required to receive approval from various environmental regulatory agencies prior to construction and/or operation of the source. Successfully navigating through the complex regulatory maze and securing necessary environmental permits in a timely fashion is paramount in keeping a project on track in order to begin construction and subsequent operation. NTH provides full scope environmental permitting services from the pre-construction air permit, to construction-based storm water and soil erosion and sedimentation control, to water discharge. NTH has developed numerous environmental permit applications for electric generation sources firing on various solid, liquid and gaseous fuels and ranging in size from 2 MW to over 1,000 MW.
Air Quality Permitting
Prior to commencing construction, an air permit must be obtained. Air Quality Services include emissions calculations, dispersion/deposition/visibility/odor modeling, regulatory applicability review, control technology analyses, human health risk assessments, and negotiation of permit terms and conditions. Services for an operational facility include Renewable Operating Permit development, and Acid Rain/Cross-State Air Pollution Rule Permit development.
Depending on where process water is obtained and ultimately discharged, a facility may be subject to a combination of withdrawal and discharge permits that must be approved prior to the activity. NTH has extensive experience obtaining applicable state/local permits for surface water withdrawal, groundwater withdrawal and discharge, and industrial stormwater discharge. Our expertise includes development of National Pollutant Discharge Elimination System (NPDES) permits for discharge associated with sand dredging, non-contact cooling and other discharges to waters of the state, as well as assessing the receiving water’s ability to assimilate more pollutant loading.
Building on or near a floodplain or wetland area incurs some extra requirements as part of the construction of a new source. NTH has assisted clients in obtaining the necessary permits including an assessment of the new facility’s ability to recover from a storm event (resiliency). In addition, NTH has completed numerous Soil Erosion and Sedimentation Control (SESC) permits for ground disturbance during construction activities. NTH also provides scheduled and unscheduled (immediately following storm events) inspections in support of SESC permits.
NTH has successfully developed and certified several permits regarding the secondary containment; distances to buildings, churches, schools, water wells, and open flames, etc. for aboveground tanks of flammable or combustible liquids or gas. Our experience includes permitting of underground storage tanks and ensuring that the appropriate steps are taken prior to installation.
