Back story
In 2016, the city of corpus Christi was audited by the Texas commission on environmental quality (
tceq) for compliance with the municipal separate storm sewer system (ms4) permit. The inspector identified a discrepancy in the number of spills reported by the emergency dispatch group and the environmental quality group. Upon further evaluation, the
stormwater
team identified the root cause.Slide6
Corrective action:
The City of Corpus Christi Coordinated Spill Response Program (CSRP) was developed in 2017 to correct a gap in spill response as recognized by the City of Corpus Christi Utilities Treatment-Stormwater team.
The CSRP is a cooperative effort between The City of Corpus Christi Stormwater Team, Police Department and Fire Department.Slide7
The problem
Prior to the program implementation, spill response to minor vehicle accidents lacked remediation; emergency response crews applied absorbent to spills and left the scene. Upon further evaluation, the Stormwater team discovered that emergency crews thought someone was coming behind them after they cleared the scene to remove and dispose of the absorbent. This thought process occurred for years resulting in motor vehicle fluids and absorbent material from minor vehicle crashes being washed directly into the receiving waters through the
stormwater
system.

Program implementation
Date of implementation: July 27, 2017
November 1, 2007-October 31, 2015:
Total spill Responses: 56
Average Per Year: 8
November 1, 2016-October 31, 2017:
Total spill responses Prior to Program Implementation: 25
Total spill responses After Program Implementation: 119
Percent Increase: 376%
November 1, 2017- may 10, 2018:
Total spill Responses: 133Slide17
Program success
The CSRP corrected all spill response gap with minimal change to response procedures.
Police dispatch operatorsnotify the stormwater Environmental Quality Specialist (EQS) team for each crash resulting in a spill of liquid other than water
police department controls traffic until scene is cleared by all parties
fire department sweeps the absorbent to the curb for pickup rather than leaving the absorbent material on the roadway
Environmental Quality team collects all absorbent for proper disposal.
Responses to incidents occurring during off-duty hours are prioritized according to severity and chance of precipitation. Slide18
Csrp: effectively awesome
Estimated Motor Vehicle Fluids Recovered Since Implementation:
528 galEstimated Absorbent Recovered Since Implementation: 20,086 lbs
based on current estimates, The CSRP is expected to prevent approximately 1080 gallons of motor vehicle fluid and 26,978 pounds of absorbent material from entering the receiving waters in 2018Slide19
