As summer fades and the rainy season creeps in, October 1st marks more than just the start of spooky season, it’s the official kickoff for stormwater compliance in California. Facilities subject to the Industrial General Permit (IGP) need to be ready for the first storm, because compliance isn’t optional, and one dirty sample can haunt your entire reporting year.

Why October 1st Matters

Rain season runs October through May, and regulators don’t wait for you to catch up. By October 1st, every facility should have their BMPs in place before the first rain hits. Once that first storm comes, you’re required to collect stormwater samples, and the results will determine your compliance path for the rest of the year.

A failed first sample can escalate your site to Level 1 or even Level 2 status, creating costly monitoring and corrective action requirements. That’s why October prep is so critical! Your first sample sets the tone for the entire season.

Don’t Let a Dirty Sample Haunt You

BMPs are your frontline defense against exceedances. Whether you’re new to the IGP or a seasoned pro, the checklist is the same:

• Wattles & Socks: Keep sediment and debris where they belong ... out of storm drains.
• Drain Filters: Capture pollutants before they flow off-site.
• Media Socks & Flocculants: Target metals, oils, and fine particulates.
• Good Housekeeping: Simple steps like sweeping, covering stockpiles, and maintaining equipment reduce risks before stormwater even forms.
  

When BMPs are in place and functioning before the first rain, you’re protecting your facility from compliance nightmares, and saving money by avoiding costly notices of violation or extra monitoring requirements.

Stock Up Before the Storm Hits

Like Halloween candy, BMPs are best purchased before the rush. Facilities that wait until the rain is falling often find themselves scrambling for last-minute supplies or paying more to expedite shipping. Planning ahead ensures your site is protected and your budget doesn’t get soaked.
