Summary
In the 1974, 34 California coastal regions were designated by the State Water Resources Control Board (SWRCB) as Areas of Special Biological Significance (ASBS) in an effort to preserve unique and sensitive marine ecosystems. Under the California Ocean Plan the SWRCB prohibited the discharge of pollution into ASBS. The Two ASBS in Monterey County are Carmel Bay and Pacific Grove, including Pacific Grove Marine Gardens Fish Refuge and Hopkins Marine life Refuge. Monterey and Pacific Grove discharge stormwater into Pacific Grove ASBS. Pebble Beach and Carmel discharge into Carmel ASBS. The prohibition of discharges into ASBS were largely ignored until the advent of stormwater discharge permits, regional stormwater plan requirements and threat of fines for non compliance. There are 348 discharges into Carmel Bay ASBS and 246 discharges into Pacific Grove ASBS. Many discharges are urban runoff from city drains, road runoff, golf course and private homes discharging from pipes and dumping directly into ocean water. Officials from Monterey Peninsula cities have been reluctant to comply with the state mandate, contending zero discharge is economically unreasonable and lacks scientific basis. All involved municipalities have filed for exemption from discharge prohibition. The exemption permit requires no alteration to the natural water quality of the ASBS and places the burden on the cities to prove no waste is entering the ASBS. While some municipalities argue over the interpretation of the California Ocean Plan, feasibility studies are being conducted for runoff diversions and stormwater recycling.
Location
Carmel Bay ASBS includes 6.2 miles of coastline from Pescadero Point to Granite Point and contains Carmel Bay State Marine Reserve and is adjacent to Point Lobos. The watershed for Carmel Bay ASBS includes the city of Carmel and extends into the Carmel Valley watershed. Pacific Grove ASBS includes 3.2 miles of coastline surrounding the city of Pacific Grove and contains Pacific Grove Marine Gardens Fish Refuge and Hopkins Marine Life Refuge. Pacific Grove lies within the Pacific Grove/Marina watershed. Discharges from Monterey and Pebble Beach are also affected.

Urban stormater runoff is the largest source of coastal pollution. Urban stormwater runoff picks up pollutants such as pathogens, heavy metals, nutrients, oil and grease, pesticides, sediments, toxic chemicals and trash from a variety of urban sources including lawns, golf courses, roads, vehicles, domestic animals and industry. Carmel Bay ASBS is a hightly productive marine ecosystem including rare species of deep water marine invertebrates and endangered sea otter. Pacific Grove ASBS is rich in tide pools, kelp forest important for supporting fish populations. The Hopkins Marine reserve is a no take area, important for supporting fish diversity and scientific research. The Central Coast Ambiant Monitoring Program has observed high levels of coliform in Carmel Bay ASBS, as well as chloride, dissolved solids and sulfate levels which exceed water quality standards. High levels of silt and sutrient pollution threaten coral that reside in Carmel Bay. 34% of sea otters tested in the region were infected with a parasite associated with cat feces and is assocaited with high levels of sea otter mortality. Shellfish from Pacific Grove ASBS contain elevated levels of heavy metals.
