Planning For Stormwater
Everyone knows planning for stormwater is crucial in keeping construction on schedule, but the time it takes to process your ATS submittal takes more proactive planning than most would expect.
Do I Need A SWPPP?
This is the golden question, and one that is in your best interest to account for! The Construction General Permit Order on www.waterboards.ca.gov states…
“Dischargers whose projects disturb one (1) or more acres of soil or whose projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity Construction General Permit Order 2009-0009-DWQ. Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility…”
Compliance with local requirements reduces pollutants as a result of stormwater discharge from the construction site. A, SWPPP, or, stormwater pollution prevention plan, is often required to remain compliant with EPA standards.
Sediment and erosion controls can prevent unwanted discharge of sediment and pollutants, such as oil and pesticides, into nearby streams and rivers. The aftermath of stormwater runoff can have a devastating effect on aquatic habitats and the environment, including your budget when regulatory fines are involved.
This is a fairly encompassing list, one that suggests a very high likelihood that your project will require a SWPPP. Now that we have clarified whether you’ll be needing one, it’s time to discuss the submittal process. This is a fairly extensive process which is why it is important to plan for major rain events, however, the infographic below breaks it down into 7 simple steps, starting from Day 1 all the way until on-site mobilization.
A general overview of your project will look like the schedule below.
• Day 1-5: ATS receives project information, including disturbed acreage, water storage volume in gallons (ponds or other water collection), and exact location. Develop and send preliminary quote.
• Day 6-16: Project owner reviews quote and provides approval to develop an ATS plan.
• Day 17-22: ATS receives water (or soil) sample, develops and delivers ATS plan.
• Day 22-25: Project Manager and QSD review ATS plan, and submit to Water Board
• Day 26-56: Water Board can take up to 30 days to review and approve the plan.
• Day 56-66: ATS revises estimate as needed, and Project Manager approves ATS installation.
• Day 67-70: ATS installs treatment system and is ready to discharge.
If we started the process today, this would be mobilized by approximately November 1st. To put this into perspective, with the stormwater season quickly approaching, it is better to have a plan in place than to be caught scrambling at the last minute to avoid unwanted releases and potential fines.
We always suggest getting an ATS plan in place well in advance on any projects where there is a risk you might need stormwater treatment. It’s cheap insurance. The plan development and associated review process is what takes most of the time, but we are here to help you every step of the way!
