The Oklahoma Turnpike Authority (OTA) is committed to preventing stormwater pollution.
OTA currently operates under three stormwater permits:
OKS0001001 [Oklahoma City Phase 1]: OTA is a co-permittee with the City of Oklahoma
City and the Oklahoma Department of Transportation (ODOT). The permit requires the
permittees to develop a Stormwater Management Program (SWMP). The SWMP includes
controls to prohibit the discharge of non-stormwater as well as controls to reduce
the level of pollutants in stormwater. The SWMP also requires an annual report.
The most recent annual report can be found at this link: http://www.okc.gov/pw/SWQ/pdf/2013_Annual_Report.pdf. OTA’s
primary responsibility under this permit is the management of stormwater runoff
from the Kilpatrick Turnpike maintenance facilities. A portion of the Turner Turnpike
is also covered under this permit. This document includes a list of activities performed
by OTA to control the level of pollutants in stormwater runoff. This permit expires
on March 14, 2018.
OKS0002001 [Tulsa Phase 1]: OTA is a co-permittee with the City of Tulsa and ODOT.
Like Oklahoma City’s permit, the Tulsa Phase 1 permit requires the permittees to
develop a SWMP and an annual report. The most recent annual report can be found
at this link: https://www.cityoftulsa.org/media/400033/FY1314AnnualReport.pdf.
OTA’s primary responsibility under the Tulsa MS4 permit is management of stormwater
runoff from the Creek Turnpike maintenance facilities. This permit expires on October
OKR04 [Small MS4]: OTA has facilities adjacent to 10 municipalities and 1 military
base where small MS4 permit requirements apply. The permit required OTA to develop
a SWMP with specified “Minimum Control Measures.” The most recent permit can be found
at this link: http://www.deq.state.ok.us/wqdnew/stormwater/ms4/phase_ii_small_ms4_final_permit_8_feb_2005.pdf.
This permit expired on February 7, 2010 and is in the process of being renewed.
In addition to meeting the conditions in the three permits shown above, the OTA
requires contractors who work on OTA projects to meet all DEQ requirements for construction
permitting and stormwater management. Usually this requires contractors to obtain
coverage under DEQ permit OKR10: Storm Water Discharges from Construction Activities.
OTA promotes good housekeeping and strives to maintain best management practices
at all of its facilities, whether covered under a permit or not. The OTA is continuously
working to improve its stormwater program. If you have any suggestions, comments,
or questions about how stormwater is managed at OTA, please contact Edward Dihrberg
at (405) 425-7449, or (888) 450-6727.
The OTA has developped a bookmark with Stormwater Pollution Prevention tips.
