Water Resource Management: Assessing Use Attainment


Integrated Report Approach

► 305(b) and 303(d) use the same data

► Data assessed once in the same manner

► Avoids conflicting conclusions

► Formalizes the use of Assessment Methods

► Expands public participation

► Encourages use of all readily available data

► Satisfies both CWA requirements with one report


Integrated Report Components

► Assessment Methods Document

► Summary of the assessment results, monitoring plan, program descriptions, and cost benefit analysis

► Integrated List of Waterbodies- all waterbodies on one of five sublists

► 303(d) List- all pollutants causing non-attainment

► Two year TMDL schedule

► Identify delisted waters


Sublists► Sublist 1: Sufficient data available to assess all applicable

designated uses and all uses are attained.

► Sublist 2: An assessment for an individual designated use indicates full attainment but other designated uses within the same waterbody are unassessed, impaired or have an approved TMDL.

► Sublist 3: Insufficient or no data to assess the designated use.

► Sublist 4: Designated use indicates non attainment due to pollutants and a TMDL has been adopted in New Jersey Register and approved by the USEPA.

► Sublist 5: Designated use indicates non attainment. The pollutant will be listed if known or as “cause unknown”.

Data RequirementsSuite of parameters required for each use assessment Minimum of eight water chemistry samples over five yearsIf two exceedances of SWQS, consider: ►Frequency of exceedance, age of data,

type of monitoring, severity of exceedance, environmental conditions, other parameters, other stations.

Can list as “not-attained” with less data than for listing as “attained”

Overall Assessment

for 2008


Assessment Unit Results

• More sampling resulted over 90% of assessment units having at least one designated use assessed

• 54% of assessment units have all of the designated uses assessed, an increase of almost 10% from 2006

• 30% increase of assessment units with all designated uses attaining

• 75% of assessment units are non attaining overall, 3% increase from 2006
