<br />Toe" (estimated to be 1.64 acres), and the Soil Barrow Area (0.65 acres) by Fall of 2009. These
<br />areas total approximately 21.1 acres.
<br />On August 29`s, 2005, DMG conducted a site inspection of lands meeting reclamation
<br />requirements. The visit was originally requested by OOSI in January of 2005 and was revised in
<br />a letter of January 4`", 2006. On January 12'", 2006, DMG released OOSI from further
<br />reclamation responsibility for Areas 6, 8, 9, 12, 14, 15, 16, 17, 19, 20 and a portion of Area 13
<br />(roads).

<br />3.0 Monitoring Activities
<br />Monitoring activities at the Logan Wash Mine during the reporting period consisted of periodic
<br />monitoring of mine water discharge and related sampling activities when necessary. These
<br />activities included (1) required flow monitoring and sampling of two National Pollution
<br />Discharge Elimination System (NPDES) outfalls on weekly, monthly, and quarterly schedules,
<br />(2) measurement of flow rates of the mine-water discharge and retort-water discharge on a
<br />quarterly basis, and (3) periodic measurement of climatic parameters (temperature and
<br />precipitation) on the Lower Bench. The latter two monitoring activities are voluntary.
<br />3.1 NPDES Outfall Sampling
<br />Two NPDES outfalls, administered by the Colorado Department of Public Health and
<br />Environment (CDPHE), were monitored in accordance with permit-established schedules.
<br />Outfall 001 (Logan Wash Mine, main lower portal [L-1 Portal] discharge) and Outfall 001
<br />(Research Mine discharge) are to be monitored weekly for pH, flow rates, total dissolved solids
<br />(TDS), and total suspended solids (TSS); monthly for TDS, TSS, pH, nitrate, sulfate, fluoride,
<br />ammonia, COD, boron, oil and grease, and phenols; and quarterly for TDS, TSS, pH, nitrate,
<br />sulfate, fluoride, ammonia, COD, boron, arsenic, copper, lead, oil and grease, and phenols.
<br />Monitoring is required at Outfall 001 when mine-water drainage from Logan Wash mine reaches
<br />a flume in "Dry Gulch" at the OOSI and BLM property boundary. Prior to 2005, monitoring was
<br />required at Outfall 002 when flow was present in a pipe discharging mine water from the
<br />Western Water 8 Land, Inc.
