The EPA recently completed their Risk and Technology Review of Petroleum Refineries, and identified some ‘residual risks’ existing under the existing monitoring standards.
To address these risks, the EPA has published a notice that they are modifying the 40 CFR parts 60 & 63 to increase monitoring requirements at Petroleum Refineries, and one of the additional requirements is for basic 10M Met towers. Met One Instruments has been providing meteorological stations to the petroleum industry for more than 30 years. Please contact us at firstname.lastname@example.org. Datasheet
