<br /> Manufactured Stormwater Treatment Measure Maintenance Plan for
<br /> Palacio Apartments
<br /> September 2014
<br /> Manufactured Stormwater Treatment Measures are PROPRIETARY treatment devices that tend to
<br /> be installed below ground and operate using some type of proprietary filter media, hydrodynamic
<br /> separation, or sedimentation and screening. Common examples of manufactured treatment
<br /> measures include manufactured media filters, inlet filters or drain inserts, oil/water separators and
<br /> hydrodynamic separators. In August 2004, the Regional Water Board's Executive Office wrote a
<br /> letter stating that a project relying on inlet filters or oil/water separators as the sole treatment
<br /> measure would be unlikely to meet the maximum extent practicable standard of the National
<br /> Polutant Discharge Elimination System Permit. See the Countywide C.3 Technical Guidance
<br /> (www.flowstobay.orq) for more information.
