+ | An [[Summaries of Environmental Topics on the Central Coast of California|environmental summary]] created by the [[ENVS 560/L Watershed Systems]] class at [[CSUMB]]. | ||
+ | |||
+ | ==Introduction== | ||
+ | Section 303(d) of the Federal Clean Water Act (CWA) requires every state to monitor the quality of water bodies and submit updated reports of impaired waters and observed pollutants of each to the United States Environmental Protection Agency (U.S.EPA) every two years. This 303(d) list identifies bodies of water in each state that do not "support beneficial uses" at that time <ref name="WB"> [https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303d_list.html / CWB (California Water Board). Central Coast Region- Clean Water Act Section 303(d) List of Water Quality Limited Segments (the 303(d) List). State Water Resources Control Board.] </ref>. These impairments are then addressed with a [[Total Maximum Daily Load (TMDL)]] control plan put forth by regional [[State Water Resources Control Board (SWRCB)]] in each state to ensure compliance <ref name="WB1">[https://www.waterboards.ca.gov/water_issues/programs/tmdl / CWB (California Water Board). 2017. Total Maximum Daily Load (TMDL) Program. State Water Resources Control Board.]</ref>. The 9 regional boards of California are shown in Figure 1. | ||
+ | |||
+ | The [[303d]] list for impaired water bodies in the [[Monterey Bay Region]] is comprised of water bodies that do not currently meet [[water quality]] goals and are therefore classified as "impaired" under section [[303d]] of the [[Clean Water Act]]. [[Beneficial uses]] are negatively impacted by pollutants which cause these impairments. Water bodies monitored for impairment are shown in Figure 2, and are listed under Section 305(d). | ||
+ | |||
+ | ==Political Process== | ||
+ | Staff of each of the nine regional water boards of California and members of the public propose new impairments in each region every two years to update the list. Regional Water Board staff then report listings to the [[State Water Resources Control Board (SWRCB)]], which then must be approved by the U.S.EPA. Every state then publishes this list every two years as the Final Integrated Report. <ref name="WB">[https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303d_list.html / WB.]</ref>. Listings proposed at regional level after 2012 are still under review, as reports are not released by calendar year and listings are delayed. <ref name="WB3">[https://www.waterboards.ca.gov/water_issues/programs/water_quality_assessment /. CWB (California Water Board). 2017. Water Quality Assessment. State Water Resources Control Board. ]</ref>]. | ||

+ | |||
+ | ==2014 303(d) List Update== | ||
+ | The most recent updates to this list are California Central Coast Water Board's recommended changes to the 2014 303(d) list. The changes were approved in 2016 by the State Water Board after a public hearing and comment period <ref name="WB">[https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303d_list.html / WB.]</ref>. | ||
+ | |||
+ | It is important to note that the list is not exhaustive, and only includes impaired bodies within the Monterey Bay Region identified up to 2014, with their associated pollutants from the Recommended Changes for The Central Coast Region's 2014 303(d) List <ref name="WB5">[https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303(d)_2014_attachments/appendix_a_changes_to_303d_list_nov2016.pdf / CWB (California Water Board). 2016. Appendix A: Proposed Changes to the 303(d) List. Central Coast Water Board approved changes to the Integrated Report (including changes to the 303(d) List and the 305(b) Report). State Water Resources Control Board.] </ref>. Proposed updates in 2014 have been indicated in the table with an (**), and will not be considered final until approved by both the California State Water Board, and the U.S.EPA <ref name="WB">[https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303d_list.html / WB.]</ref>. Observations from 1990 and 2010 have been updated in this webpage to include new impaired water bodies, new pollutants found in previously identified impaired water bodies, and removal of pollutants from previously identified impaired water bodies. | ||

− | The | + | ==Summary Table== |
+ | The following table summarizes water bodies in the Monterey Bay area <ref name= | ||
+ | "WB">[https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303d_list.html/ WB.]</ref>] that are managed by the [[CCRWQCB]] for impairments due to various pollutants. | ||
+ | |||
+ | Each waterbody is listed according to the latest year it was found with an impairment from the TMDL site <ref name="WB1"> [http://www.waterboards.ca.gov/centralcoast/water_issues/programs/tmdl/index.html / cc.] </ref> <ref name="WB">[https://www.waterboards.ca.gov/rwqcb3/water_issues/programs/tmdl/303d_list.html/ WB.]</ref>. Category 5 describes a water body where the TMDL water quality standards are not met, and TMDLs are required but not yet complete. 5A denotes that a specific pollutant does not yet have a TMDL for that waterbody, and 5B refers to pollutants that have USEPA approved TMDLs for that water body <ref name= "CAT5"> [http://www.waterboards.ca.gov/water_issues/programs/tmdl/2010state_ir_reports/category5_report.html / CWB (California Water Board). 2016.

An environmental summary created by the ENVS 560/L Watershed Systems class at CSUMB.
Contents
Introduction
Section 303(d) of the Federal Clean Water Act (CWA) requires every state to monitor the quality of water bodies and submit updated reports of impaired waters and observed pollutants of each to the United States Environmental Protection Agency (U.S.EPA) every two years. This 303(d) list identifies bodies of water in each state that do not "support beneficial uses" at that time [2]. These impairments are then addressed with a Total Maximum Daily Load (TMDL) control plan put forth by regional State Water Resources Control Board (SWRCB) in each state to ensure compliance [3]. The 9 regional boards of California are shown in Figure 1.
The 303d list for impaired water bodies in the Monterey Bay Region is comprised of water bodies that do not currently meet water quality goals and are therefore classified as "impaired" under section 303d of the Clean Water Act. Beneficial uses are negatively impacted by pollutants which cause these impairments. Water bodies monitored for impairment are shown in Figure 2, and are listed under Section 305(d).
Political Process
Staff of each of the nine regional water boards of California and members of the public propose new impairments in each region every two years to update the list. Regional Water Board staff then report listings to the State Water Resources Control Board (SWRCB), which then must be approved by the U.S.EPA. Every state then publishes this list every two years as the Final Integrated Report. [2]. Listings proposed at regional level after 2012 are still under review, as reports are not released by calendar year and listings are delayed. [4]].

2014 303(d) List Update
The most recent updates to this list are California Central Coast Water Board's recommended changes to the 2014 303(d) list. The changes were approved in 2016 by the State Water Board after a public hearing and comment period [2].
It is important to note that the list is not exhaustive, and only includes impaired bodies within the Monterey Bay Region identified up to 2014, with their associated pollutants from the Recommended Changes for The Central Coast Region's 2014 303(d) List [5]. Proposed updates in 2014 have been indicated in the table with an (**), and will not be considered final until approved by both the California State Water Board, and the U.S.EPA [2]. Observations from 1990 and 2010 have been updated in this webpage to include new impaired water bodies, new pollutants found in previously identified impaired water bodies, and removal of pollutants from previously identified impaired water bodies.
Summary Table
The following table summarizes water bodies in the Monterey Bay area [2]] that are managed by the CCRWQCB for impairments due to various pollutants.
Each waterbody is listed according to the latest year it was found with an impairment from the TMDL site [3] [2]. Category 5 describes a water body where the TMDL water quality standards are not met, and TMDLs are required but not yet complete. 5A denotes that a specific pollutant does not yet have a TMDL for that waterbody, and 5B refers to pollutants that have USEPA approved TMDLs for that water body [6].
- (*) Indicates impaired bodies and pollutants added to 2010 Integrated Report. Not exhaustive to pollutants persisting since before 2010 Integrated Report.
- (**) Indicates impaired bodies and pollutants proposed for the 2014 Integrated Report. Not exhaustive to pollutants persisting since before 2010 Integrated Report. Contains updates to previously impaired bodies, as well as addition of newly observed impaired bodies and associated pollutants between 2010 and 2014.
