General Use Level Designation (GULD): Technologies whose evaluation report demonstrates confidently it can achieve Ecology's performance goals
GULD technologies may be used in Washington and are subject to Use Level Designation conditions. We will only accept written comments on technologies that have received GULD.
Conditional Use Level Designation (CULD): Technologies that show high likelihood of meeting performance goals.
CULD allows continued use of the technology for a specified preiod of time. The vendor and/or developer must conduct field testing during the permitted time for most CULD technologies. These technologies are considered likely to attain a General Use Level.
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.
Pilot Use Level Designation (PULD): Promising technologies that need more verification testing
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. See the PULD notice of intent form for more information on PULD technologies.
