Qualitative monitoring was conducted for Outfalls A C and E during the sampling event on May 17 2016 Qualitative
monitoring was not conducted for Outfalls B & D at that time Weather conditions were not appropriate to conduct the
qualitative monitoring for Outfalls B and D at a later time, therefore we do not have records for the semi-annual period of

Dear Mr BasungLr
Phis letter shall ,eive as an update to thL May 2016 report 1 hc, Hugh Medford Municipal
Operations Center is Lurrcntly still in I ier I applicability for all outfall locations The September
2016 sampling event represents the second semi-annual storm water sampling event for the year
Storm water samples were collected from Outtalls C and E on September 19 2016 Due to recent
dry conditions, a sample could not be collected from Outfall A as there was no discharge at any
tune during or after this Storm event Up until the recent hurricane related precipitation (October
7-8 2016), the stormwater basin associated with Outtall A was below the water level necessary
for discharge to occur
Lab results were received on September 27 2016 and indicated no benchmark e-\ceedances
during this event We will continue conducting semi-annual sampling and reporting for this
location

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall
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
4 See General Permit text, Table 1, 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
detection limit, reporting limit, etc in mg/L Conversely, where fecal cohform results exceed the dilution upper limit, report the result as ">XX"

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 01 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

Dear Mr Basinger
Fhis letter ,hall serve as an update to the October 2 2017 report I Ile I Pugh Medford Municipal
Operations Center Is currently still in I mci I applicability for all outlall locations I he February
2018 sampling event represents the fir,l semi-annual ,loi nn water sampling event for the year
Storm water samples v�ere collected frown Outfalls A C and E on Febm nary 7, 2018
I-db results were received on February 16 2018 and indicated no benchmark e\ceedances for
permit-ieclumred parameters for OL[tfall A and Outfall C during this event Outfall E showed an
e-\ceedance of 112 Inng/l. for I otal Suspended Solids during this event Currently, thcrc are plans
to renovate this outfall location to reduce erosion and anv other Issues present We will continue
conducting semi-annual sampling and reporting for this location

Qualitative monitoring requirements vai y Most permits require qualitative monitoring to be

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
01 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

Qualitative monitoring requirements vary Most permits require qualitative monitoring to be

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

Dear Mi Basinger
This letter shall serve as an update to the July 5, 2017 report The Hugh Medford Municipal
Operations Center is currently still in Tier I applicability for all outfall locations The September
2017 sampling event represents the second semi-annual storm water sampling event for the year
Storm water samples were collected from Outfalls A, C and E on September 6, 2017
In addition to the standard permit -required sampling parameters, Outfall C was sampled for fecal
coliform during this event (see lab report for results) In response to elevated results, the two
catch basins that lead to the Outfall C sampling location were cleaned out by City personnel on
September 20, 2017 Both catch basins have been put on a monthly cleaning schedule and
Outfall C will be tested for fecal cohform again during the next sampling event
Lab results were received on September 13, 2017 and indicated no benchmark exceedances for
permit -required parameters during this event We will continue conducting semi-annual
sampling and reporting for this location
Sincerely,
7

sampling event represents the first semi-annual storm water sampling event for the year Storm
water samples were collected from Outfalls A, C and E on June 5, 2017
Lab results were received on June 13, 2017 and indicated no benchmark exeeedancts during this
event We will continue conducting semi-annual sampling and reporting for this location
