- 50% TSS for Separators
- 80% for Filters
http://www.njcat.org/verification-process/technology-verification-database.html http://www.njstormwater.org/treatment.html

49. NJDEP RESET ALL APPROVAL
• Most approvals were cancelled at the end of 2015 and all by end of 2016
• All manufacturers are required to resubmit new test data based on 2013
protocols
• All testing is now based on a single set of common lab based test protocols
• Any references to an approval issued prior to 2015 are now invalid and the
latest list on the NJDEP website should be used

50. WHY THE RESET?
• Initial vendors submitted 80% TSS data that was close to NJDEP protocols.
- Approval for 50% given
• Later, manufacturers worked out that there was no need to submit 80% data when
50% was the target, resulting in disparity when comparing approved flow rates

• Canada Design Spreadsheet
- Flow Rate TSS Removal
- Net Annual TSS Removal
• www.hydro-int.com/Armtec

57. NET ANNUAL & FLOW BASED SIZING
• Both use a similar Rational or TR-55 calculation
• Flow Based or Single Event – single calculation
- Usually a rainfall intensity or depth equal to 80% to 95% of annual rainfall
• Typically it is around 25mm to 37mm rainfall depth
• 1 to 2 year storm
• Calculate a peak treatment flow

58. NET ANNUAL & FLOW BASED SIZING
• Both use a similar Rational or TR-55 calculation
• Net Annual or Average Annual
- Uses long term rainfall data
• Calculates runoff rates for historic intensity groupings
• Calculates removal efficiency for each intensity grouping
• Weights groups by the frequency of occurrence over the rainfall record
period
• Sums the results for a total overall removal rate and volume treated

59. NET ANNUAL & FLOW BASED SIZING
• Single event
- More conservative
- Larger units sized as a peak water quality runoff rate is treated
• Net Annual
- Influenced by smaller events that are more frequent
- Credits TSS reduction to no runoff events
- Ideally 15 minute rainfall data should be used
- Smaller treatment units result
- No account for spring snow melt
