PHASE I ENVIRONMENTAL SITE ASSESSMENTS
A Phase I Environmental Site Assessment (ESA) is conducted to assess visual evidence of hazardous substances (including hazardous wastes and/or petroleum products) on or adjacent to the subject property that could impose an environmental liability. Most lenders require them and some city/county governments require ESAs prior to issuance of land disturbance permits or rezoning. A standard approach is used, which follows the methodology developed by the American Society for Testing and Materials (ASTM) Practice E 1527-13. The assessment is performed to identify environmental concerns that may be discerned by visual observation and information-gathering procedures.
A Phase I ESA affords you, the buyer, protection under the Innocent Landowner Defense in the event that contamination is unearthed on your property.
ESAs performed by Tallman Environmental also meet the requirements of the Federal Brownfields Law, which mandates review standards, personnel qualifications, and the level of “All Appropriate Inquiry."
WETLAND DELINEATION & 404 PERMITTING
The US Army Corps of Engineers mandates a formal delineation methodology that must be used in identifying jurisdictional water bodies, including streams and wetlands. Accurate delineation of waters on your site is a critical component of determining project permitting needs under Section 404 of the Clean Water Act. A good delineation allows maximum utilization of your property while ensuring you do not become the focus of federal enforcement case. Tallman Environmental staff have identified, field delineated, and permitted thousands of acres of wetlands throughout the eastern US. This work has been performed on over 250,000 acres of property in 12 Districts of the US Army Corps of Engineers. We maintain close connections with Corps project managers and have experience in resolving complex issues such as enforcement actions.
WETLAND MITIGATION & BANKING
Current Federal regulations require compensatory wetland mitigation for most projects impacting greater than one-tenth (1/10th) of an acre of jurisdictional wetlands and/or 100 linear feet of stream channel. Mitigation options include on-site restoration/preservation, off-site restoration, payment of an in-lieu fee or the purchase of mitigation credits from an approved mitigation bank. Tallman Environmental has extensive experience in all of these mitigation methods.
STREAM ASSESSMENT &RESTORATION
The specialty area of bank and channel stream restoration is a practical science requiring first-hand experience. Careful study and understanding of site-specific features like groundwater, soil erodibility, and biogeochemistry, within the context of upstream hydrology and native vegetation is necessary to safeguard project success. Successful stabilization and restoration of the function of these aquatic features improves both water quality and the biodiversity associated with this class of jurisdictional waters.
SEDIMENT SURVEYS
A sediment survey is conducted to assess impacts from sediment deposition over time on a body of water, such as a lake or pond. Aerial photograph review is conducted to investigate historic land use changes and possible impacts to the waterbody. Photographic documentation of the current site conditions and the survey process is also collected. Transects are established utilizing Global Positioning System (GPS) instrumentation, with sediment probing conducted at appropriate intervals along each transect. Random core samples are also collected and photographed. A report documenting the methods and findings is prepared, which includes rough calculations of amount of sediment and depths to hardpan.
PROTECTED SPECIES SURVEYS
Permitting under Section 404 of the Clean Water Act is a federal process that can frequently trigger project review under the Endangered Species Act. Consequently, surveys, relocation studies, and habitat assessment plans are often required prior to development. We are able to offer these services in conjunction with other pre-development site assessment services to lower total development costs. We can also initiate early coordination and/or informal consultation with the U.S. Fish and Wildlife Service when required by the National Environmental Policy Act (NEPA).
