The following are WQS documents from EPA's Office Of Water. Additional details for all of these recent documents are available on the internet:
http://www.epa.gov/waterscience/new.html
1. January 20, 2004- Notice of Availability of Draft Revised Human Health Criteria for Chloroform and Request for Scientific Views. The draft document would revise the applicable CWA § 304(a) criteria based on an updated risk assessment in IRIS. The update includes the new national default fish ingestion rate, a relative source contribution factor, and new bioaccumulation factors (BAFs). The “water & organisms” and “organisms only” criteria would change from 5.7 ug/L and 470 ug/L to 68 ug/L and 2,400 ug/L, respectively. DATES:EPA will accept scientific views on the draft revised chloroform criteria on or before March 22,2004.
2. January 14, 2004 - Technical Summary of Information Available on the Bioaccumulation of Arsenic in Aquatic Organisms. A final technical document that summarizes available scientific information on the amount and chemical forms of arsenic that bioaccumulate in aquatic organisms.
3. January 12, 2004 - Technical Support Document, Volume 2: Development of National Bioaccumulation Factors. A final technical document to accompany the Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health, published in 2000. The Technical Support Document Volume 2: Development of National Bioaccumulation Factors contains technical details on how EPA develops national bioaccumulation factors for use in deriving national recommended human health criteria.
4. January 5, 2004 - Final CWA § 304(a) Aquatic Life Criteria for Tributyltin (TBT). Acute and chronic criteria recommendations for TBT designed to protect aquatic life in both fresh and saltwater. TBT is an organotin compound used primarily as a biocide in antifouling paints. It is extremely toxic to aquatic life and is an endocrine-disrupting chemical that causes severe reproductive effects in aquatic organisms. TBT is extremely stable and resistant to natural degradation in water. Except possibly where a locally important species is very sensitive, freshwater aquatic life and their uses should not be affected unacceptably if the one-hour average concentration of TBT does not exceed 0.46 ug/L more than once every three years on the average (acute criterion) and if the four-day average concentration of TBT does not exceed 0.072 ug/lmore than once every three years on the average (chronic criterion).
5. January 5, 2004 - Notice of Draft Aquatic Life Criteria for Nonylphenol and Request for Scientific Views. Draft acute and chronic criteria recommendations for nonylphenol designed toprotect aquatic life in both freshwater and saltwater. Nonylphenol is an organic chemical produced in large quantities in the United States. It is soluble in water and moderately resistant to natural degradation in water. Except possibly where a locally important species is very sensitive, freshwater aquatic life and their uses should not be affected unacceptably if the one-hour average concentration of nonylphenol does not exceed 28 ug/L more than once every three years on the average (acute criterion) and if the four-day average concentration of nonylphenol does not exceed 5.9 ug/l more than once every three years on the average (chronic criterion). DATES: EPA will accept scientific views on the draft nonylphenol criteria on or before April 5, 2004.
6. December 31, 2003 - Notice of Draft Aquatic Life Criteria for Copper and Request for Scientific Views. A draft document, 2003 Draft Update of Ambient Water Quality Criteria for Copper (EPA-822-R-03-026), containing updated freshwater and saltwater aquatic life criteria for copper. These criteria revisions are based in part on new data that have become available since EPA's last comprehensive criteria updates for copper. In addition to incorporating new data, the freshwater criteria also incorporate the use of the biotic ligand model (BLM) in the criteria derivation procedures. Except possibly where a locally important species is very sensitive, freshwater aquatic organisms an their uses should not be affected unacceptably if the4-day average concentration of dissolved copper does not exceed the BLM-derived site-waterLC50 (i.e., Final Acute Value (FAV)) divided by the final acute-chronic ratio more than once every 3 years on the average (i.e., the CCC); and if the 24-hour average dissolved copper concentration does not exceed the BLM-derived site-LC50 (or FAV) divided by two, more than once every 3 years on the average (i.e., the CMC). DATES: EPA will accept scientific views on the draft revised copper criteria on or before March 1, 2004.
7. December 31, 2003 - Notice of Draft Aquatic Life Criteria for Diazinon and Request for Scientific Views. Draft acute and chronic criteria recommendations for diazinon designed to protect aquatic life in both freshwater and saltwater. Diazinon is an organophosphorus pesticide used throughout the U.S. to control insects in agricultural areas, households and urban settings. It is mobile and moderately persistent in the environment. Except possibly where a locally important species is very sensitive, freshwater aquatic life and their uses should not be affected unacceptably if the one-hour average concentration of diazinon does not exceed 0.10 ug/L more than once every three years on the average (acute criterion) and if the four-day average concentration of diazinon does not exceed 0.10 ug/L more than once every three years on the average (chronic criterion). DATES: EPA will accept scientific views on the draft revised copper criteria on or before March 30, 2004.
8. December 31, 2003 - Revised CWA § 304(a) Human Health Criteria. Updated final national recommended human health criteria for 15 pollutants: chlorobenzene, cyanide,1,2-dichlorobenzene, 1,4-dichlorobenzene, 1,1-dichloroethylene, 1,3-dichloropropene, endrin,ethylbenzene, hexachlorocyclopentadiene, lindane, thallium, toluene, 1,2-transdichloroethylene,1,2,4-trichlorobenzene and vinyl chloride. These updated criteria are based on EPA's newmethodology for deriving human health water quality criteria (i.e., the 2000 Human HealthMethodology) and supercede criteria forthese chemicals that the Agency had published earlier.The updated water quality criteria were calculated using the national default freshwater/estuarine fish consumption rate of 17.5 grams/day. Thirteen of the criteria were calculated using a relative source contribution value from the national primary drinking water standards for the same chemicals. EPA also incorporated a new cancer potency factor for 1,3-dichloropropene and vinyl chloride and a new reference dose for 1,1-dichloroethylene, hexachlorocyclopentadiene, and lindane. See Table 1 (attached).
9. November 7, 2003 - Notice of Draft Aquatic Life Criteria for Atrazine and Request forScientific Views. Revised draft acute and chronic criteria recommendations for atrazine designed to protect aquatic life in both freshwater and saltwater. EPA also released its revised Ecological Fate and Effects Risk Assessment for atrazine. Both documents incorporate EPA responses to additional information that became available after publication of the earlier draft criteria atrazine criteria document. Atrazine is an herbicide used throughout the U.S. to control weeds in agricultural crops. It is moderately volatile, soluble in water, and resistant to natural degradation in water. Except possibly where a locally important species is very sensitive, freshwater aquatic life and their uses should not be affected unacceptably if the one-hour average concentration of atrazine does not exceed 1,500 ug/L more than once every three years on the average (acute criterion) and if the Average Primary Producer Steinhaus Similarity deviation for a site is less than 5% (as determined using Comprehensive Aquatic Systems Model (CASM) or other appropriate model and index) and is not exceeded more than once every three years (or other appropriate return frequency sufficient to allow system recovery). The 5% index for the protection of the aquatic plant community should also be protective of most freshwater animals (chronic criterion). DATES: EPA will accept scientific views on the draft revised copper criteria on or before February 5, 2004.

Statewide Monitoring Coordination (Barbara Biggs, Vic Lucero)
· The Monitoring Council has a $19,000 grant ($4,000 from the Council and $15,000 from EPA) to develop a web-based map of on-going monitoring locations and associated data (what's being monitored by whom).
· The Monitoring Council has developed a second grant proposal for
$100,000 from Section 319 Nonpoint Source Funding that would be used to create a statewide data management tool that would ensure that local entities data was included in a database that would be in a useable format for the Division. No decision has been made at this time regarding what entity would maintain the database.CWCB Water Supply Investigation ( Rick Brown, CWCB)
