Another update: Have found out more information. Credit some of this to Jim Ford.
The ultimate authority controlling the landfill is the NC Dept of Nat Resources (DENR) Solid Waste. They delegate operational control to Mecklenburg Solid Waste. Mr. Charles Dial works for the latter and is responsible for twice-a-year inspections.
The Mint Hill Fire Chief said he had no authority over the landfill until such time as it actually caught fire.
DENR has a repository of PDF files related to the lansfill. Included: The most recent permit application (12/30/13), the permit itself (4/10/14), and inspection reports back to early 2010. You can see these at https://edm.nc.gov/DENR-Portal
I initially had trouble accessing this site via Chrome due to Java not being up to date. Once in, you enter the search string "60AR," which is the permit number for the landfill.
In reviewing the permit and other documents, I could find only two areas for complaint.
First, there is supposed to be an Operating Plan on file, which is to address things like projected use of landfill after completion, emergency contingency plan for firefighting, and systematic method of operation. (I was hoping the latter would address why the mass shoving of debris down the slope was OK.) I wrote the two people in DENR who granted the permit, asking where this information could be found, and never got a reply.
The other area of complaint: The slope cannot be more than 3:1, about 18 degrees. The steeper the slope the more material it takes to reach the height limit. Hard to see the slope now with all the foilage (will be much easier this winter), but got one photo from Sugar Cane that clearly shows slope of 34 degrees, twice the limit.
I e-mailed this photo to Mr. Charles Dial, who replied:
"I have seen slopes fluctuate at these sites. The goal is to achieve a 3:1 slope when you finish a cell or lift. I will discuss your observations with the facility operators at an upcoming meeting, with them."
I will see if I can post my photo on our Facebook page.
