The project required extensive coordination with Caltrans District 3. The technical study was prepared following the Caltrans and Federal Highways Administration (FHWA) protocols.
City of Escalon – General Plan Update: Air Quality, Circulation, and Land Use Elements. De Novo updated the City of Escalon’s General Plan to provide a comprehensive approach to reducing greenhouse gas and air pollutant emissions through long-term planning approaches (land use and circulation patterns and policies designed to encourage pedestrian, bicycle, and alternative modes of transportation) as well as project-level policies to ensure that projects are contributing to a walkable community with a complete streets pattern and are not exposing people in Escalon to unsafe conditions.
Post Foods, LLC – Emission Control Plan. De Novo prepared an Emission Control Plan for a Cleaver-Brooks boiler that is permitted to emit NOx at 9ppm. The San Joaquin Valley Air Pollution Control District (SJVAPCD) Rule 4320 imposed new NOx emission limits that require boilers with a total rated heat input > 20.0 MMBtu/hr to be limited to 7 ppmv of NOx by July 1, 2010. De Novo prepared and submitted an Emission Control Plan to the Air District that provided a Plan of Action to install a burner and control package to lower NOx emissions to 7 ppm allowing compliance with the Rule 4320 NOx limits. The Emission Control Plan was approved by the Air District.
Post Foods. LLC – Permit to Operate N-1933-20, Authority to Construct. De Novo prepared and submitted an Authority to Construct (ATC) to enable Post Foods, LLC to install a New CB HAWK ICS control package with parallel Positioning 7ppm ULN Burner on a Cleaver-Brooks boiler in order to comply with NOx emission limits that requires units with a total rated heat input > 20.0 MMBtu/hr to be limited to 7 ppmv of NOx. De Novo coordinated the permit effort with the SJVAPCD and the ATC was approved by the Air District.
Post Foods. LLC – Permit to Operate 2N-1933-19-3, Authority to Construct. De Novo prepared and submitted an Authority to Construct (ATC) to enable Post Foods, LLC to install a factory de-rate kit to lower the boiler fuel input to under 20 MMBtu/hr allowing compliance with the Rule 4320 NOx limits. De Novo coordinated the permit effort with the SJVAPCD and the ATC was approved by the Air District.
