This is in reference to your amendment request received March 26, 1991 for the
replacement of the coastal bermuda grass cover crop with pine trees.
Pursuant to your letter of May 3, 1991, the Division is hereby returning your project as
requested. Please be advised that an extensive review of the project was conducted by the
Division's staff; therefore, the permit processing fee cannot be returned to the Town of Conway.
If the Town of Conway wishes to pursue the use of pine trees in the future, additional
land will be required to assimilate the constituents contained in the Town's wastewater.
If you have any questions concerning this matter, please contact Mr. Mark Hawes at
919/733-5083.
