Stormwater Treatment Technologies Approved through TAPE and CTAPE


Ecology certification of a product through the TAPE program does not require local jurisdictions to accept the product for use or allow use within their boundaries. In addition to Ecology certification, local jurisdiction approval is required for installation of treatment technologies with Pilot (PULD), Conditional (CULD), or General (GULD) Use Level Designations. Local jurisdictions may choose not to accept products approved through TAPE, or may require additional testing prior to consideration for local approval.

Ecology will accept written comments on technologies that have received General Use Level Designations (GULD). Unless and until a technology has received a GULD, the submitted documents are considered work product and not available for public release. You may request copies of the final documents by filling out a Public Records Request form. Information needed for all record requests include: requester's name, phone number, company, date of request, date of requested review, report name and type of file.

Types of Stormwater Treatment Technologies Approved through TAPE AND CTAPE


 

Ecology certification of a product through the TAPE program does not require local jurisdictions to accept the product for use or allow use within their boundaries. In addition to Ecology certification, local jurisdiction approval is required for installation of treatment technologies with Pilot (PULD), Conditional (CULD), or General  (GULD) Use Level Designations. Local  jurisdictions may choose not to accept products approved through TAPE, or may require additional testing prior to consideration for local approval.

The following are the types of treatment technologies. Follow the link to each for more information, including information for the manufacturers who make them.

Pretreatment

Pretreatment is generally applied to:

Intended to achieve 50% removal of fine (50 micron-mean size) and 80% removal of coarse (125-micron-mean size) total suspended solids for influent concentrations greater than 100 mg/L, but less than 200 mg/L. For influent concentrations less than 100 mg/L, the facilities are intended to achieve effluent goals of 50 mg/L of fine and 20 mg/L of coarse total suspended solids.

Oil Treatment

Intended to achieve the goals of no ongoing or recurring visible sheen and a daily average total petroleum hydrocarbon concentration no greater than 10 mg/L with a maximum of 15 mg/L for discrete (grab) samples.

Basic Treatment

Intended to achieve a goal of 80% removal of total suspended solids for an influent concentration range of 100 mg/L to 200 mg/L.

For influent concentration less than 100 mg/L the effluent goal is 20 mg/L total suspended solids.

For influent concentrations greater than 200 mg/L a higher treatment goal is intended. Technologies listed in this section with a GULD designation are also approved for Pre-treatment in accordance with Volume V Section 6.2 of the Stormwater Management Manual for Western Washington (SWMMWW) and Section 5.2.1 of the Stormwater Management Manual for Eastern Washington (SWMMEW).

Enhanced Treatment

Intended to achieve a higher level of treatment than basic treatment. Enhanced treatment is targeted at removing dissolved metals.

Phosphorous Treatment

Intended to achieve a goal of 50% total phosphorus removal for an influent concentration range of 0.1 to 0.5 mg/L as well as achieving basic treatment.

Construction Site

Construction treatment is intended to achieve the goals of a maximum of 5 NTUs above background (background of 50 NTUs or less), not more than 10% increase in turbidity where background is greater than 50 NTUs, pH of 6.5-8.5 in freshwater and 7.0-8.5 in marine water, and no visible oil sheen.


 

Ecology's use level designation's are as follows:

GULD - General Use Level Designation

General Use Level Designation (GULD) technologies may be used in Washington subject to use level designation conditions.

CULD - Conditional Use Level Designation

Conditional Use Level Designation (CULD) allows continued use of the technology for a  specified time period during which field testing must be completed by the vendor and/or developer. Not all CULD technologies are required to conduct field testing. Units that are in place do not have to be removed after the specified time period. Use is subject to the use level designation conditions.

PULD - Pilot Level Use Designation

Pilot Use Level Designation (PULD) allows limited use of the technology to allow field testing to be conducted. PULD technologies may be installed provided that the vendor and/or developer agree to conduct field testing based on the TAPE at all installations.

Please note: Government entities covered by a municipal stormwater NPDES permit must notify Ecology when a PULD technology is proposed (form is available at PULD.pdf).
