Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On 7/7/2020 I (Daniel Boss) and Lauren Armeni conducted a follow-up compliance evaluation of the
Dana Hill WWTP.
Timed effluent composite sampling is now permitted for this facility, and so they are now in compliance
for their sampling method.
The blower motor belts now have guards covering them to prevent injury, and are no longer a safety
concern.
