Engineers Wetland Delineation and Regional Supplement Training


This training covers the protocol of the Regional Supplements in concert with the mandated 1987 Wetland Delineation Manual to identify the presence and boundaries of Waters of the United States. This training incorporates the rulings of the SWANCC and Rapanos Supreme Court decisions and the May 2015 EPA / Army Corps of Engineers ruling.

  • Covers, in detail, the knowledges necessary for one to delineate wetlands per the accepted protocols of the Army Corps of Engineers and many state and local agencies,
  • Covers in detail the applicable Regional Supplemental Methodology,
  • Covers the protocol of the May 27, 2015 EPA / ACOE directive clarifying the definition and practice of determining Waters of the United States,
  • Covers current events including the January 10, 2001, Supreme Court decision, SWANCC vs. US,
  • Covers the protocols established by the 2006 Rapanos Supreme Court decision,
  • Provides training in completing the recent 7-page waters of the US questionnaire,
  • Satisfies the training requirements of the state Departments of Transportation that require their contractors who perform wetland delineation services to have completed a Wetland Delinator Certification Program or Regulatory IV Interagency Wetland Delineation Training Course,
  • Provides approximately 2.6 semester hours toward the specialized wetland training required to become a Professional Wetland Scientist from the Society of Wetland Scientists,
  • Richard Chinn Environmental Training covers all the materials designated in the Army Corps of Engineers' Wetland Delineator Certification Program plus additional wetland management topics of interest to environmental consultants, engineers, land developers, land managers and regulatory staff,
  • Satisfies the training requirement to become a Certified Wetland Delineator, upon implementation of the Wetland Delineator Certification Program,
  • Satisfies the training requirements or recommendations to be listed by the Corps of Engineers districts as a competent wetland delineator and/or consultant on their mailing list and/or web page,
  • Is designed for the novice, the wetland manager with limited experience and the seasoned wetland manager seeking refresher re-training,
  • Is 50% (2 days) Classroom material and 50% (2 days) Field training,

  • Be able to determine if a site has hydric soils, based on in-situ field indicators
  • Be able to understand the biological, chemical, and physical features at work in wetlands
  • Be able to apply your knowledge of wetlands to other parts of the country / world
  • Be able to determine if a site is within a wetland
  • Be able to determine the boundaries of a wetland
