§ 103.8. Water pollution control.

 (a)  The number of points for water pollution control shall be based on the extent to which project implementation will eliminate detrimental effects of pollution and public health hazards from existing discharges of untreated or inadequately treated sewage.

 (b)  The following point values shall be used to determine rating points for this factor.

   (1)  Community environment and aesthetics—Use matrix in assigning points as follows:

     (i)   Category A—24 points maximum—Documented evidence or technical evaluation conducted or approved by the Department confirming that a majority of onlot disposal systems in the rated area are malfunctioning or otherwise inadequate with numerous instances of untreated or inadequately treated sewage found in publicly accessible areas; or untreated or inadequately treated sewage is being discharged to surface streams from sewers, storm drains, or overloaded sewage conveyance facilities in dry weather.

     (ii)   Category B—16 points maximum—The rated area has a documented history of a significant number of malfunctioning onlot disposal systems—this includes deficiently designed onlot systems and visual evidence of malfunctioning onlot systems primarily found in residential yards or adjacent areas; or documented intermittent discharges to surface streams from sewers, storm drains, or overloaded sewage conveyance facilities; or documented evidence of discharges of inadequately treated sewage from treatment plants to water quality limitation segments.

     (iii)   Category C—10 points maximum—Existing onlot systems in the rated area are shown to occasionally malfunction; major portions of the rated area have physical condition which limit the application of onlot disposal systems; or there is visual evidence in the project area of discharges of untreated or inadequately treated sewage from sewage conveyance facilities primarily in wet weather or other periods of peak sewage flows; or documented evidence of discharges of inadequately treated sewage from treatment plants to effluent limitation segments.

     (iv)   Category D—6 points maximum—Discharges of sewage receiving at least secondary treatment but less than NPDES requirements prior to discharge.

     (v)   Category E—0 points—Present sewerage facilities are adequate.

     (i)   18 points—Documented evidence provided by laboratory analysis that public drinking water sources or a significant number of private drinking water sources are contaminated by malfunctioning onlot disposal systems or that downstream drinking water sources are subject to water quality standards violations due to discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation.

     (ii)   10 points—Documented contamination of public or private groundwater drinking water sources supported by known subsurface soil and hydrogeologic conditions and evidence of periodic water source contamination or documentation that downstream drinking water sources are periodically subject to contamination by existing discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation, based on water quality analyses or evaluation of the stream’s physical characteristics, or both.

     (iii)   5 points—Suspected contamination of public or private groundwater drinking water sources based on knowledge of subsurface soil and hydrogeologic conditions or a downstream drinking water source is shown to be affected by periodic water quality standards violations from discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation based on evaluation of the stream’s physical characteristics.

     (iv)   0 points—No downstream drinking water sources or no documentation or evidence that drinking water sources are affected by the sewage treatment need which would be eliminated or upgraded by project implementation.

   (3)  Fish and aquatic life. Points awarded in the fish and aquatic life category shall be assigned as follows:

     (i)   14 points—Surface waters are capable of supporting a cold or warm water fishery but documented evidence shows that they are not because of pollution caused by discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation.

     (ii)   8 points—Surface waters currently supporting a depressed cold or warm water fishery shown through documentation to be caused by untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation.

     (iii)   5 points—Surface waters currently supporting a cold or warm water fishery documented to be periodically affected or threatened by discharge of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation based on evaluation of the stream’s physical characteristics.

     (iv)   0 points—No documentation or evidence that fish and aquatic life are affected by untreated or inadequately treated sewage discharges which would be eliminated or upgraded by project implementation.

   (4)  Public bathing. Points awarded in the public bathing category shall be assigned as follows:

     (i)   8 points—A downstream permitted public bathing beach has been closed due to contamination as a result of water quality standards violations due to discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation.

     (ii)   3 points—A downstream permitted public bathing beach is shown through water quality analysis and an evaluation of stream and bathing area’s physical characteristics to be subject to contamination by untreated or inadequately treated sewage discharges which would be eliminated or upgraded by project implementation.

     (iii)   1 point—A public bathing place permit has been denied because of violations of water quality standards resulting from discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation.

     (iv)   0 points—No downstream public bathing uses are documented or there is no documented effect of discharges of untreated or inadequately treated sewage on downstream public bathing uses which would be eliminated or upgraded by project implementation.

   (5)  Boating and recreation. Points awarded in the boating and recreation category shall be assigned as follows:

     (i)   5 points—Documentation shows that discharges of untreated or inadequately treated sewage which would be eliminated or upgraded by project implementation prevent the use of a stream or impoundment for boating and other nonswimming and nonfishing recreational purposes due to excessive aquatic growth or other material posing a danger to the user or his equipment.
