Tulsa NPDES Monitoring
• EMC Data
from 1994 to 2010
• Median annual TP range
(1994-2010):
0.15 mg/L to 0.47 mg/L
• Median value for
2009 — 2010 was 0.30 mg/L

Urban Stormwater BMP Performance
Data for TP
Various types of properly
designed, constructed and
maintained urban stormwater
BMPs can provide significant
reductions in total phosphorus
concentrations.
