Subject: Leona Quarry and Chimes Creek contamination

Hello Keith,

Here's an update of the ongoing problems we are seeing from the Quarry development.  Martin tells me you are still waiting for the results of the water quality test and the revised SWPPP.  In the meantime, it appears to us living by the creek that there is some experimentation going on at the expense of our environment.

Mark,
The City responded and determined that the newly installed baker tank was being used, pumping water into the storm system after being filtered inside the tank. We determined that the filter system in the tank was insufficient and installed a filter bag  at the outflow of the tank. Also, I have asked DeSilva Gates Construction to install another filter bag at the outflow pipe placed inside the manhole of the storm system.

Note, with the first filter installed, the color of the water leaving the
tank was clear.

Thank you for calling this matter in our attention.
