3. Background Coal Operators required by PADEP Monitor (and if necessary, Mitigate) stream flow losses and/or pooling Monitor (and if necessary, Mitigate) stream flow losses and/or pooling due to full extraction underground mining due to full extraction underground mining No. 563-2000-655 “Surface Water Protection – Underground Bituminous No. 563-2000-655 “Surface Water Protection – Underground Bituminous Coal Mining Operations” effective Oct. 8, 2005. Known as “TGD” Coal Mining Operations” effective Oct. 8, 2005. Known as “TGD” Dramatically increased number of streams that needed monitored Dramatically increased number of streams that needed monitored (to include all streams that contain at least two biological taxa) (to include all streams that contain at least two biological taxa) Dramatic increase in frequency of monitoring Dramatic increase in frequency of monitoring

4. Stream Condition Monitoring (SCM) - the process of identifying the various states of flow or “condition” of stream segments. Types of Monitoring SCM involves traversing a stream from its downstream confluence to its headwaters Determine the starting and end point (distance) Various stream flow regimes such as flow, puddle, pool, dry, and non-continuous flow.

5. Stream Condition Monitoring FLOWINGDRY POOLPUDDLENON-CONTINUOUS FLOW

6. Flow Monitoring - development of a discharge value at an established point for use as a hydrological baseline. Types of Monitoring Direct Flow Measurements are taken at specific locations along each stream Location based on access, proximity to mining operations, and stream characteristics. Flow measurements are currently being gathered at over 800 locations.
