Environmental Services in Our North Carolina Office

July 8, 2022

It is with great pride that we highlight our Asheville, North Carolina office—ClearWater, an EnviroScience Company—and two of its many areas of expertise: remediation plans and implementation for Notices of Violation (NOV) and bat surveys.

Clement RiddleFormerly known as ClearWater Environmental Consultants, Inc., the office was founded, owned, and operated by Clement Riddle since 2002. When EnviroScience acquired the company last fall, we knew that under Clement’s leadership, his team of four had tremendous potential. And we weren’t wrong—the office is thriving and continues to grow! Now at six staff members, we are always looking to add key personnel to enhance and increase our capacity and capabilities.

EnviroScience Office in Asheville, North Carolina

Rooted in our core values of TeamworkClient AdvocacyRespectAccountabilityQuality, and Safety, every EnviroScience office strives to provide high-quality, region-specific natural resource and environmental services. Our North Carolina office is no exception, offering top-notch expertise in services that include: wetland delineation; threatened and endangered species surveys; 401/404 permitting; NEPA/SEPA environmental assessments; remediation plans and implementation for notices of violations; and wetland and stream mitigation planning and monitoring.

With over 30 years of experience managing complex projects, EnviroScience experts have a rich understanding and familiarity with environmental laws and regulations, as well as an outstanding reputation with these regulatory agencies. Because most of our employees have over ten years of experience in their respective fields, our team’s collective knowledge and diverse backgrounds—paired with state-of-the-art equipment and cutting-edge technologies—afford our clients innovative, cost-conscious solutions. We always put our clients’ needs first and only use necessary resources, allowing us to reliably complete projects on time and within or below budget.

EnviroScience Employees at the ClearWater Office in Asheville, NCAbiding by the same credo, our North Carolina office holds its assets and values to the same standard, carefully selecting highly specialized and capable employees when staffing and consistently delivering first-rate services. These practices are evidenced by the master service agreements we hold with clients in the transportation, energy, and manufacturing industries, as well as municipal, state, and federal agencies. 


ClearWater, an EnviroScience Company, has helped over one hundred clients successfully resolve Notices of Violation or Unauthorized Activity. These notices can result from unexpected weather events, rogue contractors, or unintentional misunderstanding of plans or permit conditions.

The team at our North Carolina office is experienced in evaluating sediment impacts to streams and conducting forensic evaluations of site conditions. This includes preparation of remediation plans, oversight of cleanup work, regulatory coordination with staff from North Carolina Department of Environmental Quality (NCDEQ) or U.S. Army Corps of Engineers (USACE), and final documentation and reporting.



Bats represent one-quarter of all mammal species worldwide. Of the 17 species that occur in North Carolina:

  • Three are federally endangered:
    • Virginia big-eared bat (Corynorhinus townsendii virginianus)
    • Gray bat (Myotis grisescens)
    • Indiana bat (Myotis sodalis)
  • One is federally threatened: Northern long-eared bat (Myotis septentrionalis)
  • Ten are listed as Species of Greatest Conservation Need (2015 NC Wildlife Action Plan).

Projects located within the range of protected bat species may require coordination with the U.S. Fish and Wildlife Service (USFWS). Bat populations are surveyed by a variety of methods including: mist-netting; acoustic recording; trapping; roost monitoring; portal searches; bridge and cave inspections; and radio telemetry. These surveys can be used to determine presence or probable absence of threatened or endangered bat species.

EnviroScience biologists are highly experienced and qualified to conduct bat surveys in North Carolina and hold USFWS Recovery Permits for threatened and endangered bats. EnviroScience has over 20 years of experience performing bat surveys for state and federally listed species, and helping clients comply with USFWS and state regulatory agencies. Our team provides expertise with the coordination and permitting process for Endangered Species Act (ESA) Section 7 Consultation, the development of Habitat Conservation Plans, and development of natural resources and conservation management plans. 

Northern long-eared bats are currently under review to be uplisted to endangered by November, 2022. Should this uplisting transpire, EnviroScience can help navigate your projects through the bat survey process.
