Stormwater Pollution Prevention Plan (SWPPP) Taylor Creek Stream Restoration

Construction Stormwater Pollution Prevention Plan Template The Maryland Department of the Environment (MDE) requires construction operators to develop a Stormwater Pollution Prevention Plan (SWPPP) prior to submitting a Notice of Intent (NOI) for Construction General Permit (20-CP) coverage (Refer to Part III.F of the permit). To assist with developing a SWPPP that meets the minimum requirements of the General Permit for Stormwater Associated with Construction Activity, the Maryland Department of the Environment has provided this template.

This template is customizable to your specific project and site.

Once MDE has approved coverage for your project under the 20-CP, include your NOI, your authorization, and a copy of the 20-CP as attachments to the SWPPP.

For more information on the Tier II Checklist, the NOI in ePermits or Cationic Chemical Treatment, please navigate to our website located here:

https://mde.maryland.gov/programs/water/wwp/Pages/gp_construction.aspx

Instructions for Using the SWPPP Template Each section of the SWPPP Template includes instructions and space for your project and site information. Read the instructions for each section before you complete that section. The blue text indicates what information is to be included.

The SWPPP Template is an editable document file. You may add tables or additional text and/or delete unneeded or inapplicable fields. The information provided in each section may vary in length.

The following items may help you better prepare for completing the SWPPP:

● Make sure you read the General Permit thoroughly before you begin preparation of your SWPPP. By doing so, you are ensuring that you have a working understanding of the permit’s underlying requirements.

● Remember to complete the SWPPP prior to submitting your Notice of Intent (NOI) for permit coverage when required.

● If there is more than one construction operator or individual/entity that will be responsible for separate phases or parts of the construction for your project, consider coordinating the development of your SWPPP with the other operators or individuals/entities.

While MDE has made every effort to ensure the accuracy of all instructions contained in the SWPPP Template, it is ultimately the permit that determines the obligations of regulated construction stormwater discharges. In the event of a conflict between the SWPPP Template and any corresponding provision of the 20-CP, you must abide by the requirements in the permit. MDE welcomes feedback on the SWPPP Template. Future revisions of this document will consider all feedback.

SECTION 3: DEWATERING AND USE OF CHEMICAL TREATMENT (Part III.F.2.c of the permit)

3.1 Dewatering Practices

General Filter bags will be used at the site to filter stream water that is not captured by the clear water diversion or pump-around practice. They will be installed in accordance with the approved ESC plans. Filter bags will be regularly inspected to ensure no rips or punctures in the bag and that the connections remain watertight.

Specific Dewatering Practices

Filter bag

Description: Geotextile bag through which sediment laden water is filtered

Installation Upon project start

Maintenance Requirements

Monitor bags for rips, tears, or punctures and replace bag if damaged. Ensure the dewatering hose connection to the bag is watertight. Dewater to stabilized area or suitable base per approved plans.

Outlet protection

Description: Velocity dissipator and/or outlet protection (riprap or sandbags)

Installation Upon project start

Maintenance Requirements

Outlet protection practices will be monitored to ensure that flow from the stream diversion pipe/clean water pump-around is not causing channel erosion and/or creating turbidity greater than the allowable threshold.

Turbidity Meter and Procedures

Meter: Oakton T100WL

Calibration: Calibration verification occurs prior to every use. If the calibration is more than 2% off the sample vials, a full calibration will be conducted. Procedures are outlined in the instruction manual that accompanies the meter in the carrying case. All calibration will be in accordance with manufacturer’s instructions.

Sampling: Sampling will occur at every discharge point during dewatering. A sample will be collected in a clean vessel and the sample vial will be filled to the 4/5 position. After filling, the

Instructions – Describe any dewatering practices Include a description of all dewatering practices that are installed and maintained at the construction site.

Excavations Trenches Foundations Vaults or other similar points of accumulation cap will be tightly secured. Before measuring, the sample vial should be gently shaken to produce a uniform sample. Wait until all the bubbles have disappeared and wipe the vial surface with a soft cloth to ensure the surface is dry, clean, and free of smudges. Apply 1-2 drops of silicon oil to the surface and wipe with a soft cloth to obtain an even distribution.

Place the meter on a level flat surface and insert the vial into the meter for reading.

Reporting and compliance: Turbidity sampling will be conducted by a third-party contractor.

Information will be recorded on the turbidity monitoring sheets provided by MDE in the “Turbidity Reporting” section of the SWPPP binder. If the NTU’s are above the acceptable threshold, the contractor will stop pumping and begin corrective measures. Corrective measures will be documented.

Inspection Report Forms

Standard MDE inspection forms will be used.

5.2 Corrective Action (Part III.D of the Permit)

Corrective action is dictated by the severity of the violation. Items or violations that have not resulted in sediment leaving the site are issues a minor maintenance order. If these items are not completed by the next scheduled inspection (two weeks typically), they will be escalated to a correction notice. If the correction notice is not address in the outlined time frame, a stop work order will be issues.

In a situation where large quantities of sediment are observed leaving the site due to negligence or contractors are working out of sequence/ purview of the plans, an immediate stop work order will be issues.
