Notice: This form and any information attached to it are Puouc necoms as oeuneu ni rv� oene
available for inspection and examination by any person upon request (NC General Statute 132-6).
Instructions:
• Prepare one form for each individually monitored unit.
• Please type or print legibly.
Attach a notification table with values that attain or exceed INC 2L groundwater standards or NC 2B surface water standards. The notification
must include a preliminary analysis of the cause and significance of each value. (e.g. naturally occurring, off -site source, pre-existing
condition, etc.).
Attach a notification table of any groundwater or surface water values that equal or exceed the reporting limits.
Attach a notification table of any methane gas values that attain or exceed explosive gas levels. This includes any structures on or nearby the
facility (NCAC 13B .1629 (4)(a)(i).

e No. No groundwater or surface water standards were exceeded.
Yes, a notification of values exceeding a groundwater or surface water standard is attached. It includes a list of groundwater and surface water
monitoring points, dates, analytical values. NC 2L groundwater standard. NC 2B surface water standard or NC Solid Waste GWPS and
preliminary analysis of the cause and significance of any concentration.
❑ Yes, a notification of values exceeding an explosive methane gas limit is attached. It includes the methane monitoring points, dates, sample
values and explosive methane gas limits.
Certification
To the best of my knowledge, the information reportetl and statements matle on this data submittal and attachments are true and correct.
Furthermore, I have attached complete notification of any sampling values meeting or exceeding groundwater standards or explosive gas
levels, and a preliminary analysis of the cause and significance of concentrations exceeding groundwater standards. I am aware that there
are significant penalties for making any false statement, representation, or certification including the possibility of a fine and imprisonment
