6 Regulatory Drivers 2010 changes to 25 Pa Code (m) PCSM long-term operation and maintenance requirements All permits issued after dates below must contain a PCSM plan w/ O&M instructions Individual Permits after 11/2010 General Permits (PAG-02) after 12/2012 6

7 Regulatory Drivers PennDOT s Individual Statewide MS4 Permit Applies to urbanized areas Ensure that NPDES PCSM BMPs are implemented, operated, and maintained consistent with applicable Chapter 102 regulations. 7

Current Practices 1 in 4 DOTs have a complete SCM inventory and inspection/maintenance plan For most DOTs, maintenance is performed on an as-needed basis for common

8 Current Practices 1 in 4 DOTs have a complete SCM inventory and inspection/maintenance plan For most DOTs, maintenance is performed on an as-needed basis for common indicators Typical practices: removing excess sediment revegetating ditches and embankments trash removal emergency response when impaired conveyance threatens roadway safety 8

9 Current Practices What about functionality and performance? Requires knowledge of the SCM s purpose and various functional elements Training is essential 9

10 SCM Inventory Where are all of the SCMs (and what are they)? Information rich, data poor SCM data mostly only existed on PCSM plans Data not centralized 10

11 SCM Inventory Phase 1 Desktop Review Began with projects permitting circa 2006 and later 500+ projects w/npdes permits reviewed or currently under review for SCMs 11

12 SCM Inventory Phase 2 Field Reconnaissance Additional plan/data mining (add vegetated swales) GPS locating and information gathering 12

13 SCM Inventory Data collected for each SCM: SCM type Lat./Long. District/County/Municipality SR/Segment/Offset Receiving water data Urbanized/non-urbanized NPDES permit data Year constructed ECMS number Surface area, DA treated, IA treated Access type/visibility 13

14 SCM Inventory 14

15 SCM Inventory 1,650 SCMs have been inventoried to date Does not include vegetated swales because substantial additional effort Does not include other certain types of nonstructural or restoration BMPs Estimated 3,000 existing SCMs in total Includes vegetated swales and SCMs that have not yet been geo-located 15

16 SCM Inventory SCMs with county and District boundaries 16

17 SCM Inventory SCMs with roads and watersheds 17

22 SCM Maintenance Policy Why? Districts are currently maintaining SCMs in accordance with each PCSM Plan Standardized practices needed inspections maintenance documentation PA Stormwater BMP Manual recommendations not suitable Adding roughly 170+ SCMs per year to the inventory* *Not including vegetated swales and restoration BMPs 22

23 SCM Maintenance Policy Immediate Implementation Standardized inspection protocol Regular maintenance cycles Consistent documentation Inventory procedure Training! Long-term Plan Improve efficiency Expand data tracking Analyze data to improve practices 23

Inspections - SCM Maintenance Policy Condition assessment Establishes a baseline condition and uncovers any issues that may result in reduced effectiveness or failure of

24 Inspections - SCM Maintenance Policy Condition assessment Establishes a baseline condition and uncovers any issues that may result in reduced effectiveness or failure of the SCM Visual screening Detects existing/potential problems and their source to determine if corrective maintenance is needed and/or if further investigation is required 24

25 Maintenance - SCM Maintenance Policy Routine preventative maintenance Needs to be performed on regular cycles and can be scheduled far in advance of the work. Corrective maintenance Needs are uncovered through visual screenings, condition assessments, and preventative maintenance activities. 25

26 Technology Implementation Maintenance IQ Visualization of database and links to documents Accessible to all w/cwopa account No GIS licensing Maintenance personnel using for other applications 26

27 Technology Implementation Applications for tablets/laptops Handheld inspection checklists with automated data upload Electronic payroll entry 27
