CMAR point and grading system

CMAR point and grading system. (1) Applicable sections. The department shall determine which CMAR sections under s. NR 208.04 (5) apply to each treatment works and shall make the sections available electronically to the treatment works owner no later than April 30 of each year. (2) Section scores and grades. A point score shall be calculated by the department for only the CMAR sections that apply to a specific wastewater treatment works. The score and grade for each CMAR section shall be based on information and data collected and provided by the owner of the treatment works for the prior calendar year. The point score for each CMAR section shall be calculated by subtracting any points generated in each CMAR section from 100. The point score from each section shall be used to determine the applicable grade and response action shown in table 1 for that CMAR section. (3) CMAR sections and point assignments. CMAR sections shall be assigned points based on treatment works monitoring data and other information from the previous calendar year as shown in this subsection. The department may require other section specific information that may be included within each CMAR section. Supplemental questions and information may not include points and may not affect the section’s grade. (a) Influent flow and loading. Point assignments for exceedances of percentages of maximum month design flow and 5-day biochemical oxygen demand (BOD) loadings in the previous calendar year shall be determined as follows: (b) Effluent quality and plant performance (BOD/CBOD). 1. Point assignments for WPDES permit limit exceedances and for percentages of effluent 5-day biochemical oxygen demand (BOD) or 5-day carbonaceous biochemical oxygen demand (CBOD) limits in the previous calendar year shall be as follows: 2. For systems that discharge intermittently to waters of the state, the points per monthly exceedance for this CMAR section shall be based upon a multiplication factor of 12 months divided by the number of months of discharge. (c) Effluent quality and plant performance (total suspended solids -TSS). 1. Point assignments for WPDES permit limit exceedances and for percentages of effluent TSS limits in the previous calendar year shall be as follows: 2. For systems that discharge intermittently to waters of the state, the points per monthly exceedance for this CMAR section shall be based upon a multiplication factor of 12 months divided by the number of months of discharge. (d) Effluent quality and plant performance (ammonia- NH3). 1. Point assignments for exceedances of monthly WPDES permit limits for effluent ammonia (NH3) in the previous calendar year shall be as follows: 2. If monthly limits do not apply and the applicable ammonia limits in a permit are weekly, then point assignments related to exceedances of weekly WPDES permit limits for effluent ammonia (NH3) in the previous calendar year shall be as follows: (e) Effluent quality and plant performance (phosphorus -P). 1. Point assignments for exceedances of monthly WPDES permit limits for effluent total phosphorus (total P) in the previous calendar year shall be as follows: 2. For systems that discharge intermittently to waters of the state, the points per monthly exceedance for this CMAR section shall be based upon a multiplication factor of 12 months divided by the number of months of discharge. (f) Effluent quality and plant performance (total nitrogen-total N). 1. Point assignments for exceedances of monthly WPDES permit limits for effluent total nitrogen (total N) in the previous calendar year shall be as follows: 2. For systems that discharge intermittently to waters of the state, the points per monthly exceedance for this CMAR section shall be based upon a multiplication factor of 12 months divided by the number of months of discharge. (g) Groundwater quality. Point assignments associated with groundwater dischargers with groundwater monitoring wells shall be as follows: (h) Ponds and lagoon leakage. Point assignments shall be as follows: (i) Biosolids quality and management. Point assignments shall be as follows: (j) Staffing and preventative maintenance. Point assignments shall be as follows: (k) Operator certification and education. Point assignments shall be as follows: (L) Financial management. Point assignments shall be as follows: (m) Sewage collection systems. 1. Point assignments shall be as follows: 2. Owners of sewage collection systems shall record and maintain information about the operation and maintenance of their sewage collection system, which may include the following: cleaning, root removal, flow monitoring, smoke testing, sewer line televising, manhole inspections, lift station servicing, manhole rehabilitation, mainline rehabilitation, private sewer inspections, private sewer infiltration/inflow (I/I) removal, precipitation, sanitary sewer overflows, building or basement backups, lift station failures, sewer pipe failures, complaints, and any other collection system information deemed important by the owner. (n) Grading summary. The department shall provide to the owner a summary of section grades, response ranges and resultant grade point average for the applicable completed CMAR sections under s. NR 208.04 (5) (a) to (m) .
