June Workshop Feedback

Emissions ranked highly as being important or quite important Scored consistently in the middle of the range against most of the principles, Scored well on risk basis (2nd to Environmental Impact) Concerns about complexity Considered applicable for larger emissions (data quality) Identified that potential for double charging (e.g. CO2 emissions under ETS and CRC)

Proposal

Use the EA’s emissions module as a basis What are givens: Will look at the amount and the “hazard potential” e.g. toxicity / BOD etc. Threshold value below which excluded

Example – Dry Cleaners

Would not attract additional charges for emissions

Example – Medium Size Sewage Treatment Works

Emissions charge would be based on water discharges

• nly (if above threshold)

Example – Power Station

Emissions charge potentially applied for: Air Water Discharge Water Abstraction Air emissions likely to be dominant

Key Questions

Actual versus Permitted If Actual Emissions: What timeframe (previous 3 years - discuss)? Did consider plant capacity but considered that this is not helpful / relevant for many sites Banding versus Continuous Changes in Cost?

Key Question 1: Permitted vs Actual

Pros Cons Permitted Stable, defined, easily accessed, provides incentive to tighten limits. Limits tighten too far – breaches, frequent variations,

• ld limits. No active review of

licence then potential blocks “spare” capacity to others. Actual Provides incentive to reduce actual emissions, remains flexible Uncertainty in measurements. Potential to consider if “I” can afford it I can pollute.

Key Question 2: Banding V Continuous Changes in Cost

Pros Cons Banding Reflects there are potentially large uncertainties in measurement, Not responsive to changes, Continuous Reflects even small positive changes, More IS/data management / verification. Less Stable - variable between periods.
