Item Summary:
The FM 3406 Roadway Improvement Project will widen the existing roadway from an undivided four -lane roadway to a four -lane
divided roadway with curb and gutter sections. This project is located in the Edwards Aquifer Recharge Zone and is under the
control of the Texas Commission for Environmental Quality's (TCEQ) Edwards Aquifer rules related to storm water runoff. The
City Manger approved the Edwards Aquifer Recharge and Transition Exception Request for TCEQ on August 24, 2012.
Following further coordination with the Texas Department of Transportation, the water quality treatment method for this project
was changed. The maintenance agreement for the Storm Trooper unit will be now be used instead of the provision for
vegatative filter strips that was included in the transition request approved on August 24, 2012.
The signature of the City Manager is needed on Form TCEQ-0600 Attachment G to formalize this change.

StormTrooper Maintenance Guidelines:
A preventative maintenance cleanout schedule is the most valuable tool for maintain the proper
operation of StormTrooper. Separator maintenance costs will be greatly reduced if a good housekeeping
plan for the property is developed i.e., trash pickup, lawn maintenance, dumpster control, etc.
StormTrooper separators have no moving parts and no filter cartridges. The manufacturer recommends
quarterly ongoing inspections for accumulated pollutants. Pollutant deposition may vary from year to
year. Quarterly inpsections ensure that the system is serviced at the appropriate times. Table 4 lists
recommended maximum capacities of oil and sediment. Professional vacuum services should be
considered when capacities exceed these recommended levels.

Inspection Procedures
1. Easiest observation and maintenance is best accomplished during non -flow (dry weather)
conditions 3-4 days after the most recent rain.
2. Remove interceptor covers or open hatchway to observe conditions. Remove hatchway
safety net ("EnterNet"). Observe for trash and debris and remove if necessary. This is the
most important maintenance requirement. If absorbent pillows ar utilized, observe their
condition. Uniform browning or gray color of the pillow means they should be replaced.
Observe baffle debris screen and clean if necessary.
3. Coalescing plates are self-cleaning and seldom require maintenance unless damaged. Do
not walk or stand on plate packs. Call ParkUSA (888 -611 -PARK) for replacement parts.
4. Check the depth level of oil and sediment with a tank sampler device designed for this
purpose.
