' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
" See General Permit text, Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format, "<XX mg/L", where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to he
performed during a "representative storm event" or during a "measureahle storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Please verify whether Qualitative Monitoring musthe performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to he
performed during a "representative storm event" or during a "measureable storm event." however, E
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge From the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval From the local DWQ Regional Office.

'For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit text, Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format, For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format "<XX m L", where XX is the numerical value of the

2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
° See General Permit text, Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example jo not report Below Detection limit, BDL, <PQL, Non --detect, ND, or other similar non -
numerical format, When results are below the applicable limits, they must be reported in the format, "<XX_mgjL", where XX is the numerical value of the
detection limit, reporting limit, etc, in mg/L.
Note: if you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.

As required by the referenced permit in condition Part III, Section E.1, attached are the original
and one copy of the signed discharge monitoring report (DMR) and laboratory analytical results
for the month of September 2014 for the Georgia-Pacific Wood Products LLC, Dudley Sawmill
facility (GP). The facility instituted "Pier Two Analytical Monitoring in July 2014 as a result of
two consecutive periods where valid sample results were above benchmark values for TSS.
Sample results for July and September 2014 indicated TSS was still above benchmark limits.
The facility continues to implement the required actions under the Tiered response plan as
outlined in previous submittals. Additionally, the benchmark sampling exceedance is the fourth
occurrence during the permit term; therefore, the lacility is now in Tier Three Monitoring. As a
result; an engineering firm has also been contracted to evaluate the existing stormwater controls
and make recommendations on any additional controls needed.
Should you have any questions or need additional information, please contact the Complex
Environmental Manager, Brandy Long, at [phone] or [e-mail].
