Answer Key
, 1. [WI-SMOL-E2-Q1] Northwoods Pumping Co operating at 1500 N 3rd St, Superior, WI 54880
in 2026 handles 560 gallons of septage with 133 mg/L nitrogen. Regarding Chemical toilet
waste characteristics, what does Wisconsin code require?
A. No manifest needed under 560 gallons – manifest required for all loads in Wisconsin.
B. Records kept 1 year only – WDNR requires 5-year retention.
C. Apply on frozen ground if under 133 acres – prohibited when frozen/snow-covered.
D. Per Chemical toilet waste characteristics: WDNR requires compliance with NR 113/114 – 560 gal load must
meet 133 ft setback/application limits with Grade L master supervision.
Rationale: Correct D. For Wisconsin Septage Master Operator Grade L, Chemical toilet waste characteristics
under NR 113/114 governs. Example Northwoods Pumping Co scenario with 560 gallons and 133 mg/L:
Wisconsin requires certified Grade L operator, proper manifest, setbacks, seasonal restrictions, 5-year logs.
Why others wrong: Manifest always required, frozen ground application prohibited, Grade L cannot be
substituted by Grade T, records 5 years not 1, soil eval required, DOT placarding required. This reflects
2026/2027 WDNR update.
2. [WI-SMOL-E2-Q2] Dairyland Septage operating at 1201 E Washington Ave, Madison, WI
53703 in 2024 handles 639 gallons of septage with 58 mg/L nitrogen. Regarding Holding tank
vs septic, what does Wisconsin code require?
A. DOT placard not needed for septage – required for bulk waste transport.
B. Per Holding tank vs septic: WDNR requires compliance with NR 113/114 – 639 gal load must meet 58 ft
setback/application limits with Grade L master supervision.
C. No manifest needed under 639 gallons – manifest required for all loads in Wisconsin.
D. Apply on frozen ground if under 58 acres – prohibited when frozen/snow-covered.

3. [WI-SMOL-E2-Q3] Great Lakes Waste operating at 500 S 7th St, La Crosse, WI 54601 in 2026
handles 3220 gallons of septage with 27 mg/L nitrogen. Regarding Metals and contaminants,
what does Wisconsin code require?
A. Per Metals and contaminants: WDNR requires compliance with NR 113/114 – 3220 gal load must meet 27 ft
setback/application limits with Grade L master supervision.
B. Grade T operator may supervise Grade L site – Grade L requires Grade L certified operator.
C. No manifest needed under 3220 gallons – manifest required for all loads in Wisconsin.
D. DOT placard not needed for septage – required for bulk waste transport.
Rationale: Correct A. For Wisconsin Septage Master Operator Grade L, Metals and contaminants under NR
113/114 governs. Example Great Lakes Waste scenario with 3220 gallons and 27 mg/L: Wisconsin requires
