Summary

Baldwin Park bans illicit discharges and illicit connections to its municipal storm drain system under Municipal Code Chapter 52. Violations are misdemeanors punishable by up to $1,000 and six months in jail, and the city can also charge them as infractions with escalating fines.

(A) No person shall cause or allow an illicit discharge to enter the municipal storm water system. (B) No person shall place, dump, dispose, litter, accumulate, maintain, discharge, or cause to enter into the MS4 any pollutant or any foreign object such as batteries, tires, waste receptacles, yard debris, refuse, rubbish, food waste, chemicals, animal waste or oil cans, which are also considered illicit discharges.

Full Breakdown

05. 05(B) specifically bars dumping batteries, tires, yard debris, food waste, chemicals, animal waste or oil cans into the system. 06 separately bans maintaining or using an illicit connection, such as a floor drain or pipe that conveys non-storm water into the MS4, and requires the connection's owner to remove or disable it once discovered. 04. 09. 11. 13. 15(A), the Chief Executive Officer, the Director or a designee may inspect private premises on 24 hours' oral or written notice, or with no notice if exigent circumstances exist, to trace discharge points, examine drainage, sample runoff, and check for illicit connections. 16(A) and file a detailed written report within ten calendar days describing the cause, timing, type, concentration and volume of the discharge.

Violations & Fines

Under Section 52.15(B), a Chapter 52 violation is a misdemeanor carrying a fine of up to $1,000 or up to six months in county jail, or both, though the City Prosecuting Attorney may instead charge it as an infraction: $100 for a first offense, $200 for a second, and $250 for each violation after that. Violators must also reimburse the city for all cleanup, investigation, administrative and legal costs, including attorneys' fees. Each day a violation continues, and each separate discharge, counts as a new, separately punishable violation. Unpaid nuisance-abatement costs become a lien against the property under Cal. Gov't Code §§ 38773.1 and 38773.5.

Frequently Asked Questions

What counts as an illicit discharge in Baldwin Park?
Section 52.05(B) defines it broadly: dumping or allowing batteries, tires, yard debris, food waste, chemicals, animal waste, oil cans or other pollutants to enter the storm drain system is an illicit discharge, unless the material is exempted under the city's NPDES permit or a separate state permit.
How much can I be fined for a stormwater violation?
Section 52.15(B) sets a misdemeanor at up to $1,000 and six months in jail, but the City Prosecuting Attorney can instead pursue it as an infraction at $100 for a first offense, $200 for a second, and $250 for each additional offense.
Do construction sites need special stormwater paperwork?
Yes. Under Section 52.11, a site covered by the state's General Construction Activity Storm Water NPDES Permit must keep its Notice of Intent, SWRCB waste discharge ID number and Storm Water Pollution Prevention Plan on site and retain them for three years after construction ends.
Can the city inspect my property for stormwater compliance?
Yes. Section 52.15(A) lets the Chief Executive Officer, the Director of Public Works or a designee enter and inspect private premises on 24 hours' notice, or immediately if exigent circumstances exist, to check drainage, discharge points and possible illicit connections.
