Not all industries discharging wastewater into the City of Shreveport's sewer collection system will be required to obtain an Industrial User Permit.
Each industry must be evaluated individually based on several factors including characterization of waste, amount of discharge flow, and whether or not the facility is subject to any categorical regulations.
The first step is to submit a completed Application form, which can be downloaded from the previous page.
When filling out the application form, be sure the include all information that is requested and that the information is as complete and updated as possible.
Once the application has been submitted to the pretreatment office, an inspector will contact you to discuss the application further.
Attached to the industrial user application form is a fee schedule for permit fees ($1000 for five year Significant permit, $500 for five year Non-significant permit, $200 for temporary).
In addition to the permit fee the facility will be required to test their wastewater at set intervals outlined in the permit. The cost of the periodic sampling events will vary greatly depending on how many and what kinds of parameters are listed in the facility's permit as well as the lab chosen to do the work. There are several independent labs in the Shreveport area to choose from.
Industries permitted by the City test as often as four times a year and as little as once a year.
It depends of how the industry is classified (General, Non-significant or Significant Industrial User). The parameters that will be required to test for depend solely on the characterization of the waste being discharged.
That determination will be made based on the information that is submitted in the application form
Included in the City's Ordinance Section 94-142 is an outline of various violations and methods of handling them.
Enforcement actions range from Notice of Violations, Compliance Schedules to Administrative Orders and Fines.
The following questions pertain to restaurant grease traps:
What size grease trap do I need?
The size of a grease trap depends largely on the type of business and how much waste is produced. The more waste produced usually means the bigger the grease trap will need to be. Consider the following in sizing a grease trap:
• Type of food being prepared
• Seating Capacity
• Retention time needed for efficient removal of grease
• Frequency of maintenance
• Accessibility of trap
• What equipment will be connected to the trap?
The City of Shreveport's Ordinance Section 94-213 gives the following formulas for determining the minimum size of interceptors:
1. Twelve (12) hour operation or less
Seating Capacity X 7 gallons = Minimum size of interceptor
2. Over twelve (12) hours of operation
Seating Capacity X 7 gallons X 2 = Minimum size of interceptor
To be effective, grease traps must be cleaned out regularly and the contents completely removed. The frequency of cleaning the grease trap and pumping out grease and solids will depend the nature and volume of the wastewater.
Inside traps should be cleaned weekly.
• Bail out any water to facilitate cleaning
• Dip the grease out of the trap and put in a water tight container
• Scrape grease from all sides and lid.
• Place grease container in trash receptacle
• Note: Clean grease trap the day before trash is picked up to avoid nuisance complaints.
Outside traps should be inspected monthly.
• Use a "dip stick" to measure grease layer.
• Contact pumper to clean out trap
• Be sure the pumper scrapes all sides and that all trap contents are removed
• Inspect the trap for potential problems while it is empty
