This is a 2007 NPDES permit (MI0045713) reissued to BFI Waste Systems for the Arbor Hills Remediation Area in Northville, Michigan, authorizing discharge of treated groundwater and compost runoff to an unnamed tributary of Johnson Creek. The permit specifies effluent limitations for parameters including CBOD5, suspended solids, ammonia nitrogen, phosphorous, mercury, and volatile organic compounds, with monitoring and reporting requirements. The permit was effective June 1, 2007, and expired October 1, 2011.
Key data point: No specific quantitative factual reading (measured temperature, CO level, or violation) is stated in this template document; it is a procedural permit issuance with permitted discharge limits and monitoring parameters.

This is a 2006 fact sheet for BFI Waste Systems' NPDES wastewater discharge permit (MI0045713) for the Arbor Hills Remediation Area groundwater treatment system. The document describes the facility's treatment infrastructure, receiving water (unnamed tributary to Johnson Creek), existing effluent quality data from May 2005–May 2006, and proposed effluent limitations for various pollutants including BOD, ammonia, suspended solids, and volatile organic compounds. A public comment period was announced for February–March 2007.
Key data point: No specific urgent or substantive data point. Document is a procedural permit fact sheet with historical effluent data (BOD5 max 21 mg/L, ammonia max 13 mg/L, benzene 0.0 mg/L) but no temperature, CO, or violation readings relevant to landfill overheating or air quality concerns.

BFI Waste Systems applied in 2006 to renew NPDES Permit MI0045713 for the Arbor Hills Remediation Area in Northville, Michigan. The facility operates a groundwater treatment system including purge wells, gradient control wells, a Kinetico treatment unit, an aeration ditch, and two aeration ponds that treat approximately 60 gallons per minute of groundwater and discharge to an unnamed tributary of the Johnson Drain. The application documents the facility's groundwater remediation operations and treatment processes.
Key data point: No specific factual readings reported. This is a permit application and renewal form documenting the facility's operational structure and treatment processes, not a monitoring or inspection report with measured data.

MDEQ laboratory analysis of seven water and compost samples from Arbor Hills Landfill (ONYX) collected in October 2005, testing for volatile organic compounds, base/neutral/acid compounds, pesticides, PCBs, and inorganic parameters. Most results are non-detected; detected compounds include trace chlorinated hydrocarbons, metals, and nutrients in ppb/ppm ranges typical of landfill leachate.
Key data point: Detected analytes include 1,1-dichloroethane (9.6 ppb, ONYX-INF), benzene (1.1 ppb, ONYX-INT), cis-1,2-dichloroethylene (16–17 ppb), and vinyl chloride (3.6–4.0 ppb); arsenic ranging 4.7–14 µg/L; lead detected at 1.8 µg/L; TOC at 18–140 mg/L across samples.

A December 2005 DEQ Water Bureau post-inspection report documents a wastewater treatment facility (Onyx Arbor Hills LF) treating contaminated groundwater and compost runoff. The inspection on 10/25/05 found satisfactory conditions across most operational and monitoring areas. However, the report details 12 active effluent violations spanning from January 2004 to May 2005, involving exceedances of BOD, ammonia, total nitrogen, total solids, and phosphorus limits.
Key data point: 12 active effluent violations (BOD, ammonia, nitrogen, total solids, phosphorus) from January 2004 – May 2005; highest measured: 202 mg/l total solids (permit limit 30 mg/l), 111.1 lbs total solids (permit limit 25 lbs/day), ammonia 0.72 mg/l (permit limit 0.5 mg/l).

DEQ Water Bureau conducted a Compliance Sampling Inspection on October 25–26, 2005, of the remediation area east of Arbor Hills Landfill under NPDES Permit No. MI0045713. All tested parameters met effluent limitations at the time of sampling, but the site reported six exceedances in the prior 12 months (January–May 2005), primarily in Total Phosphorus and CBOD5, likely from compost pile runoff.
Key data point: Six NPDES permit exceedances reported in past 12 months: Total Phosphorus at 1.4 mg/L and 0.96 lbs/day (limits 1.0 mg/L and 0.8 lbs/day, January 2005); CBOD5 at 21 mg/L and 14.3 lbs/day (limits 10 mg/L and 8.3 lbs/day, May 18, 2005).

This is a pre-inspection report for the Onyx Arbor Hills Landfill (Permit MI0045713) dated October 2005, documenting a planned Compliance Evaluation Inspection. The facility treats contaminated groundwater and compost pile runoff, discharging to an unnamed tributary via Outfall 001A. The report identifies eight active effluent violations spanning 2004–2005 for total solids and phosphorus exceedances in both loading and concentration limits.
Key data point: Eight active effluent violations detected 2004–2005: Total Solids up to 202 mg/L (limit 30 mg/L) and Phosphorus up to 1.4 mg/L (limit 1.0 mg/L), Outfall 001A.
