Cooper Stands Ready
for good neighbor

The rule requires a large portion of the reciprocating compression fleet in the United States above 1,000 hp to operate at no more than 3 g/bhp-hr NOx emissions for 2-stroke cycle lean burn engines, 1.5 g/bhp-hr NOx for 4-stroke cycle lean burn engines, and 1 g/bhp-hr NOx for 4-stroke cycle rich burn engines by mid-2026. Cooper understands that requirements associated with the Good Neighbor Rule, particularly the horsepower limit and narrow implementation window, have come as a surprise to many in the industry, and that there is great concern around the cost and speed at which these engines can be upgraded.
