RE: PHASE I AND II WATER QUALITY MONITORING PLAN UPDATED ATTACHMENTS
WHITE STREET LANDFILL - PHASE II, PERMIT NO. 41-03
GREENSBORO, NORTH CAROLINA
Dear Mr. Sugg,
On behalf of the City of Greensboro, Golder Associates NC, Inc. (Golder) is submitting the enclosed updates to the Water Quality Monitoring Plan for the Phase I and Phase II waste units at the White Street Landfill.
These updates are in response to an email from Perry Sugg of the North Carolina (NC) Department of Environmental Quality (DEQ) Division of Waste Management - Solid Waste Section to Michael Plummer of
HDR, Inc., dated June 19, 2017.
The June 19, 2017, email stated that upon a final review of the Water Quality Monitoring Plan and Landfill
Gas Monitoring Plan submitted with the revised May 2017 application for the Phase II C&D Landfill, the following comments are to be addressed before approving:
Landfill Gas Monitoring Plan
 Add the Landfill Gas Monitoring Data form (revised – March 6, 2017), which is to be filled
out for each landfill gas monitoring event.
Water Quality Monitoring Plan
 In Appendix I, Table 1A should be revised by removing the word “proposed” from the title
 In Appendix I, Table 1B should be revised by removing the word “proposed” from the title
 In Appendix I, Table 1B should be revised by replacing groundwater monitoring well II-4 with II-4A
 In Appendix I, Table 1B should be revised by adding groundwater monitoring well II-7B
 In Appendix I, Table 1B should be revised by adding surface water monitoring point SW-1
 In Appendix I, Table 1B should be revised by adding a note that indicates that surface water monitoring points SW-1, SW-2, SW-3, SW-4, and SW-5 serve as part of the
monitoring program for both the Phase I and Phase II landfills
 In Appendix II, Figure 1 should be replaced with a better and clearer map that shows the
current Phase I and Phase II groundwater monitoring network
 In Appendix II, Figure 2 should be replaced with a better and clearer map that shows all of
the surface water monitoring points
 In Appendix II, add a site facility map that shows all of the solid waste units
In response to these comments, the Landfill Gas Monitoring Data form will be used for quarterly boundary migration monitoring, which will continue to be performed as directed in Section 4.3.3 of the Landfill Gas
