City of Corpus Christi: Stormwater Infrastructure Metrics 02/2018 Number of Inlets: 18,228 Number of Outfalls: 2364 Miles of Active Stormwater Mains-Underground: 636.4 Miles of Stormwater Mains Under Construction: 21.4 Miles of TxDOT Stormwater Mains: 95.3 Miles of Concrete Ditch: 22.4 Miles of Main Earthen Ditch: 66.4

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.

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.

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.

Strategic implementation Identify key players Define non-negotiables Organizational alignment Change culture Measure effort Visible proponents

Key players: Roles and Responsibility Hazmat team Hazard identification; liaison Stormwater Environmental quality Environmental spill response and remediation Ensure proper disposal enforcement Dispatch Central communicator for all teams Fire department Second on scene Pollution mitigation: Dam, dike, divert or sorbent application Police Department First on scene; Notifies dispatch of spill Traffic control

Non-negotiables effectively utilize current staff cannot impede current response time Minimal change to response procedures imperative cost effective sustainable Clear rules and responsibilities

Organizational alignment Identify concerns for all involved Identify clear objective Develop response strategy

Change culture Change attitude Increase awareness Coordinated Training for pollution prevention First responders City wide facilities Hazmat Environmental quality Facility personnel Demonstrate program effectiveness

Measurable efforts Program Justification Quantifying the benefit of proper response for any spill Number of motor vehicle accidents resulting in loss of fluid other than water Approximate gallons of motor vehicle fluids recovered Approximate lbs of sorbent and debris recovered

Visible proponents Creating a standard that will be adhered to Police chief Fire chief Environmental services superintendent Risk management manager

Key elements Communication Fire Department Police Department Utilities Hazmat Team Water Quality Improvements Capturing majority of petroleum based pollutants from minor motor vehicle accidents Capturing majority of motor vehicle debris

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: 133

Program success The CSRP corrected all spill response gap with minimal change to response procedures. Police dispatch operators notify 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.

Csrp: effectively awesome Estimated Motor Vehicle Fluids Recovered Since Implementation: 528 gal Estimated 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 2018
