Re: Appendix I Inorganic Constituent Exceedances
Foothills Environmental Landfill
Permit # 1403-MSWLF-1998, DIN 26546

Dear Mr. Roger Watts:

The Solid Waste Section (Section) has reviewed groundwater monitoring data for the Foothills
Environmental Landfill. This letter is being sent in regards to all lined landfills. Concentrations of Appendix
I inorganic constituents were reported above the standards established in 15A NCAC 02L .0202 (2L
Standards) in on-site monitoring wells. Detection monitoring is currently being conducted at the facility
in accordance with 15A NCAC 13B .1633 and additional action is necessary based on the inorganic 2L
Standards exceedances. Rule 15A NCAC 13B .1633(c) instructs the facility owner or operator to perform
one of two actions in response to 2L Standard exceedances:

• 15A NCAC 13B .1633(c)(2) states that the owner or operator “Shall establish an assessment
monitoring program meeting the requirements of this Section within 90 days except as provided
for in Subparagraph (3) of this Paragraph.”

Or

• 15A NCAC 13B .1633(c)(3) states that the owner or operator “May demonstrate that a source
other than a MSWLF unit caused the exceedance, or the exceedance resulted from an error in
sampling, analysis, statistical evaluation, or natural variation in ground-water quality. A report
documenting this demonstration shall be approved by the Division. A copy of this report shall
also be placed in the operating record. If a successful demonstration is made, documented, and
approved by the Division, the owner or operator may continue detection monitoring. If after 90
days, a successful demonstration is not made, the owner or operator shall initiate an
assessment monitoring program as required by this Section.”

Based on the results of the aforementioned monitoring data, the Section instructs the Foothills
Environmental Landfill to either implement an assessment monitoring program or prepare and submit an
alternate source demonstration within 90 days of receipt of this letter. If the alternate source
demonstration is successful and approved by the Section, the facility may continue detection monitoring.
If the Section does not approve the Alternate Source Demonstration, the facility should initiate
assessment monitoring in accordance with 15A NCAC 13B .1634.

Please contact me at 919-707-8245 or [e-mail] or the hydrogeologist assigned to
your landfill if you have any questions or concerns regarding this correspondence. Thank you in advance
for your cooperation in this matter.

Sincerely,

Ellen Lorscheider
