2018 Update to TAPE Guidance Documents
You may still be able to use the 2011 guidance, see submitting treatment technologies process section above for more information.
Between versions: What changed and what stayed the same?
This is a general list of some of the major changes, please note this list is not exhaustive.
- New pre-approved testing facilities
- Number of qualifying storms increased
- TAPE fees increased
- Nitrogen and bacteria added as screening parameters
- Long detention guidance document added as an appendix
- Requirement to submit data electronically (Excel or csv file)
- Options for influent data that falls outside of the TAPE influent concentration range
- Additional size categories for particle size distribution analysis
- Requirement to measure accumulated sediment within the technology (where feasible)
- Requirement to evaluate pollutant removal as a function of flow rate and bypass frequency over time
- Pollutant removal as a function of flow rate analysis based on 90th percentile influent flow rate
- Clarified discrete flow sampling method
- Definition of qualifying storm
- Required pollutants
- Performance goals
- Statistical analysis methods
- QA/QC requirements
- Use Level Designations
Pre-Approved Technology Evaluation Facilities
The below pre‐approved facilities have adequate pollutant concentrations and flows that enable manufacturers to use as a monitoring site. Using these facilities will reduce the overall cost of monitoring a device and allows smaller companies to participate in the TAPE program. These sites have experienced, on‐site monitoring staff to perform the sampling and analysis activities that also make the evaluation more efficient.

Evaluating new technologies
We review engineering reports on the performance of new technologies and provide our use-level designations in the approved technologies table.
Board of External Reviewers (BER)
To help us with evaluations, a paid Board of External Reviewers (BER) provides national expertise in stormwater treatment technologies. The BER acts in a direct review capacity to provide us recommendations about each new technology and how well it performs.
Each application to TAPE and C-TAPE will be assigned a minimum of three members from the BER to provide detailed review and comment on the applications, Quality Assurance Project Plans (QAPPs), and Technical Evaluation Reports (TERs).
We evaluate several types of permanent stormwater treatment systems for specific sampling criteria, site and technology information, quality assurance and quality control measures, target pollutants, and evaluation report content.
These types of treatments are intended to achieve:
The following table lists the devices that have received a designation through the TAPE process.
In addition to our certification, local jurisdiction approval is required (and not guaranteed) for installation of treatment technologies we have evaluated and given a use designation.
Functionally equivalent technologies
We have approved the following technologies as functionally equivalent to best management practives (BMPs) included in our stormwater management manuals. These technologies did not pass through TAPE.
