Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 aor)roval from the local DWO Reeional Office.

Please verify whether Qualitative Monitoring must be performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 Re
a] Office.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require Qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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
i
permitted site outfall. The previous measurable storm event must have been at least 72 hours i
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 must be performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary, Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 must be performed during a "representative storm
event" or 'measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 outfail. 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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event"or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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
E 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.

Was this a "Representative Storm Event" or " Measureable Storm Event" as defined by the permit?
(See information below.)
yYes Q No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary, Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 1.0 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the z
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.
By this signature, I ce Fy that this report is accurate and complete to the best of my knowledge:

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureabte 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.
s 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 lylonitoring must be performed during a "representative storm
event" or "measureable storm event" (requ(rements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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
0A 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 must be performed during cC W +storm
event' or "measureable storm event" (requirements vary, depending on th��rmrt .
Qualitative monitoring requirements vary, Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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
i
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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

event" or "measureable storm event" (requirements vary, depending on the �TW&L FILES
CTION
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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
0.2 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.

Memo
To: Public Works Staff
CC: Chris D. Ray, Director
From: Tony Rose, Stormwater Superintendent
Date: 10/28/2014
Re: Tier 2 Response
We took stormwater samples at Outfall # 1 on April 15, 2014 and September
24, 2014. Both samples registered above the Total Suspended Solids (TSS)
limit of 100 mg/ L. The April sample TSS level was 220 mg/ L and the
September sample, following maintenance efforts in June, was 130 mg/ L.
The steps taken in June to lower the TSS level were not effective enough to
reach under the limit of 100 mg/ L.
The following additional items were completed between October 2, 2014 and
October 23, 2014 to improve the entire site and the drainage area for the site:
• Removed all rip -rap from detention pond and check dams
• Removed all silt fence
• Removed trees around detention pond and approximately 30' x 100'
along the outside of the chain link fence
• Cleaned and graded detention pond and swell along the outside of the
chain link fence (approximately 30' x 100)
• Installed new liner & rip -rap in bottom of detention pond up to the
discharge level
• Installed new check dams (approximately 3) along chain link fence
• Installed sod in 30'x100' graded area, the areas between the check
dams, and a 30' circumference around the detention pond
• Installed #5 stone along the inside of chain link fence from pole barn
to light pole approximately 10' out and covered any bare areas with
stone
• Installed sediment filter fabric on invert of 6" discharge pipe
• Installed additional check dams at the rear of the pole barn
• Added approximately 50' of silt fence material and #5 stone along and
behind pole barn
• Re -graded discharge ditch to form sloping side walls; seeded, matted
and placed straw

• Installed 15" black corrugated pipe in pathway to improve access to
site for landscaping and maintenance crew
• Aerated and overseeded outfall area with a fescue/rye blend from the
fuel containment area to the sodded area
• Installed silt fence around topsoil stockpile behind the fence
The following table details the material costs and labor:

$481.06
Wheat straw - 11 bales
$27.50
15" Corrugated black pipe
$140.00
Grand Total
$9,160.35
Total number of labor hours = 242.5
Total cost of labor = $7,044.15
Total cost of materials = $2,116.20
We will collect the next stormwater sample after November 7, 2014. This will
allow 2 weeks for the sod and grass seed time to stabilize the area. Hopefully,
all of these improvements to the detention pond area will reduce the Total
Suspended Solids to an acceptable level. See attached pictures. Additional
progress pictures are located on the server Y drive.
Action Plan
1) Collect 3 monthly samples (Nov 7-30, Dec 1-31, Jan 1-31). Report to
DWQ.
2) Clean detention pond with vacuum trailer, including changing the
sediment filter fabric monthly.
3) Continue with monthly outfall inspections.
4) No parking lot box blading during collection period.

Please verify whether Qualitative Monitoring must be performed during a "reRrWPnFCzVA-fVgrn
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be�
performed during a "representative storm event" or during a "measureable 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 must be performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable 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 aooroval from the local DWO Rezional Office.
