SUPPLEMENTARY INFORMATION:

A. Does this action apply to me?

    Entities potentially regulated by this action include a wide 
variety of privately-owned CII facilities such as shopping centers, 
office complexes, warehouses, private schools and hospitals, and 
various manufacturing facilities. Entities affected by this action are 
located within either of two watersheds in Los Angeles County, in 
California: the Los Cerritos Channel/Alamitos Bay Watershed or the 
Dominguez Channel and Los Angeles/Long Beach Inner Harbor Watershed. 
This description of affected entities is not intended to be exhaustive, 
but rather provides a guide for readers regarding entities likely to be 
affected by this action. This description of affected activities 
includes the types of entities that EPA is now aware could potentially 
be affected by this action. Other types of entities not included could 
also be affected. To determine whether your entity is affected by this 
action, you should also review the description of EPA's action in 
documents online at the website listed in the section C below. If you 
have questions regarding the applicability of this action to a 
particular entity, consult the person listed in the FOR FURTHER 
INFORMATION CONTACT section.

B. Summary of Final Designation

    In the Final Designation, EPA has determined that stormwater 
discharges from certain CII sites in the Los Cerritos Channel/Alamitos 
Bay and Dominguez Channel and Los Angeles/Long Beach Inner Harbor 
Watersheds in Los Angeles County are contributing to violations of 
water quality standards and require NPDES permit coverage under the 
CWA. The Final Designation differs from the Revised Preliminary 
Designation of November 2, 2023 (88 FR 75282) in that EPA is not 
designating privately-operated facilities at the Ports of Long Beach 
and Los Angeles at this time. EPA is taking a phased approach to this 
Final Designation such that EPA may consider designating stormwater 
discharges from additional CII sources in the future.
    This Final Designation is in response to two September 15, 2015 
petitions entitled ``Petition For A Determination That Stormwater 
Discharges From Commercial, Industrial, And Institutional Sites 
Contribute To Water Quality Standards Violations in Dominguez Channel 
and the Los Angeles/Long Beach Inner Harbor (Los Angeles County, 
California) and Require Clean Water Act Permits,'' and ``Petition For A 
Determination That Stormwater Discharges From Commercial, Industrial, 
And Institutional Sites Contribute To Water Quality Standards 
Violations in the Alamitos Bay/Los Cerritos Watershed (Los Angeles 
County, California) And Require Clean Water Act Permits'' as well as an 
order from the U.S. District Court for the Central District of 
California in Los Angeles Waterkeeper v. Pruitt, 320 F. Supp.3d 1115 
(C.D. CA 2018).
    EPA's Final Designation is made pursuant to CWA sections 
402(p)(2)(E) and (6) and EPA's implementing regulations at 40 CFR 
122.26(a)(1)(v) and 40 CFR 122.26(a)(9)(i)(D) that authorize EPA to 
designate stormwater discharges for regulation under the NPDES 
permitting program that are contributing to violations of water quality 
standards but are not otherwise

required to be permitted under EPA's stormwater regulations.
