CATLIN personnel regularly interact with State and Federal environmental regulatory
agencies throughout the Southeast, but most frequently with EPA Region IV, NCDENR
and the GA EPD due to the high volume of projects that we have in progress in these

Our engineers, geologists and scientists routinely coordinate with regulators to ensure
that our clients and sites are in regulatory compliance. We have established
relationships with regulators throughout the Southeast and also assist with the
development of environmental regulations and policies. CATLIN’s president, Mr.
Richard G. Catlin, was previously appointed by the Governor to serve on the NC UST
Council and also chaired the Joint Committee on Environmental Practice by
Professional Engineers and Licensed Geologists in North Carolina. The committee
was instrumental in formulating and recommending modifications to the North
Carolina Groundwater Quality Standards. Mr. Catlin also provided input to the former
North Carolina Department of Environmental Management (DEM) and the GA EPD
during the development and implementation of UST regulations and was invited by
the DEM to participate in policy making efforts as related to the NCAC, Subchapter 2L
Groundwater Standards.
