Pace Analytical Services, LLC is committed to providing high quality results and exemplary customer
service to our clients. Pace acknowledges the failure on our behalf to deliver a TSS sample result for
sample Outfall-1 (4/29/20) collected 04/29/20 22:45. There was a lab accident with the TSS test that
impacted the batch which made it impossible to provide a sample result.
This failure to provide a result has prompted Pace to reassess our TSS processes.
Please do not hesitate to contact me or Kevin Herring if you have any questions or require additional
information.
Sincerely,
Barry Johnson

' 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.
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.
"See General Permit text, Table 3 or Table 4, identifying protected receiving water classifications where the more protective TSS benchmark applies.
s Stormwater discharges into receiving waters classified as saltwater are subject to the second listed benchmark.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, NO, 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, quantitation 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.
