Emissions allowance price indications under the Cross-State Air Pollution Rule finished the week ended Dec. 15 unchanged to higher.
After jostling around earlier in the week, seasonal nitrogen oxide, or NOx, allowances for 2017, as of Dec. 15, were marked in a bid-and-offer spread of $140 to $200, with the midpoint unchanged from the week prior but the spread widening from a previous level of $150 to $190.
During the week ended Dec. 15, Cross-State Air Pollution Rule, or CSAPR, seasonal NOx allowances for 2018 were quoted in a bid-and-ask range of $115 to $200, with the spread widening from a range of $125 to $180 a week earlier.
In May, CSAPR 2017 seasonal NOx prices rallied above $700 after buyers began to hedge ozone season emissions ahead of the peak summer cooling season. But an overall mild summer in many regions of the country, particularly the Northeast, led to tepid interest, which offered pressure to seasonal NOx allowance prices in September and part of October.
CSAPR 2017 annual NOx allowances were unchanged on the week in a bid-and-offer spread of $1 to $3.
CSAPR 2017 Group 1 sulfur dioxide, or SO2, allowances were unchanged on the week, pegged at a level of 25 cents to $4. Group 2 SO2 allowances for 2017 were also firm in a bid-and-offer spread of 25 cents to $5.
