1 am writing on behalf of the City of Charlotte — Sweden Road Shop facility, which operates under
Certificate of Coverage No. NCG080840 to discharge stormwater from the facility into surface waters.
We are requesting to be granted a waiver from monitoring associated with the permit through the end of
March 2023.
Currently, Outfall 002 is in Tier II monthly monitoring, and Outfalls 001 and 003 are monitored quarterly
as required by the permit effective July 1, 2021. Right now, a significant construction project is
underway which may impact all outfalls on site. This construction project consists of the demolition and
repaving of a large portion of asphalt and concrete on site. While erosion and sedimentation control
measures will be used according to the site's erosion control plan, and all measures will be inspected and
maintained, we are concerned that the construction project will inevitably result in some sediment loss
that will affect sampling results. For this reason, we are requesting to temporarily suspend monitoring
until the project is completed.
We will, of course, continue with sampling as required by the permit until we hear further from your
office. Once the project is complete, we will monitor the site closely and address any additional concerns
according to permit conditions.
Thank you for considering our request. Please contact me at [phone] or at
andrew.decristofaro(a)charlottenc.gov if you would like to discuss this request in further detail.
Respectfully,
