TMDL Pollutant: Siltation

Total Waste Load Allocation:      Total Load Allocation:
Explicit Margin Of Safety:      Implicit Margin Of Safety: N
Units for Total Waste Load Allocation and Total Load Allocation:      TMDL Pollutant Source Type: Point/Nonpoint Source
TMDL End Point: THE MOST STRINGENT NARRATIVE CRITERIA APPLICABLE IS THE FISH & AQUATIC LIFE USE CLASSIFICATION. FOR MAINTAINING BIOLOGICAL INTEGRITY, THE WATERS SHALL NOT BE MODIFIED THROUGH THE ADDITION OF POLLUTANTS OR THROUGH PHYSICAL ALTERATION TO THE EXTENT THAT THE DIVERSITY AND/OR PRODUCTIVITY OF AQUATIC BIOTA WITHIN THE RECEIVING WATERS ARE SUBSTANTIALLY DECREASED OR ADVERSELY AFFECTED, EXCEPT AS ALLOWED UNDER 1200-4-3-.06. THE INTERPRETATION OF THIS PROVISION FOR ANY STREAM WHICH (A) HAS AT LEAST 80% OF THE UPSTREAM CATCHMENT AREA CONTAINED WITHIN A SINGLE BIOREGION AND (B) IS OF THE APPROPRIATE STREAM ORDER SPECIFIED FOR THE BIOREGION AND (C) CONTAINS THE HABITAT (RIFFLE OR ROOTED BANK) SPECIFIED FOR THE BIOREGION, MAY BE MADE USING THE MOST CURRENT REVISION OF THE DEPARTMENT¿S QUALITY SYSTEM STANDARD OPERATING PROCEDURE FOR MACROINVERTEBRATE STREAM SURVEYS AND/OR OTHER SCIENTIFICALLY DEFENSIBLE METHODS. INTERPRETATION OF THIS PROVISION FOR ALL OTHER STREAMS, PLUS LARGE RIVERS, RESERVOIRS, AND WETLANDS, MAY BE MADE USING RAPID BIOASSESSMENT PROTOCOLS FOR USE IN WADEABLE STREAMS AND RIVERS (EPA/841-B-99-002) AND/OR OTHER SCIENTIFICALLY DEFENSIBLE METHODS. EFFECTS TO BIOLOGICAL POPULATIONS WILL BE MEASURED BY COMPARISONS TO UPSTREAM CONDITIONS OR TO APPROPRIATELY SELECTED REFERENCE SITES IN THE SAME BIOREGION IF UPSTREAM CONDITIONS ARE DETERMINED TO BE DEGRADED. FOR HABITAT, THE QUALITY OF INSTREAM HABITAT SHALL PROVIDE FOR THE DEVELOPMENT OF A DIVERSE AQUATIC COMMUNITY THAT MEETS REGIONALLY BASED BIOLOGICAL INTEGRITY GOALS. THE INSTREAM HABITAT WITHIN EACH SUBECOREGION SHALL BE GENERALLY SIMILAR TO THAT FOUND AT REFERENCE STREAMS. HOWEVER, STREAMS SHALL NOT BE ASSESSED AS IMPACTED BY HABITAT LOSS IF IT HAS BEEN DEMONSTRATED THAT THE BIOLOGICAL INTEGRITY GOAL HAS BEEN MET.
