The Commission wants to hear from you!
To provide oral public comment during a hearing you will need to sign up to provide public comment when you register for the hearing (via Zoom). If public comment slots fill up, comments will be heard from those that signed up first. Sign-up closes the morning of the meeting. Registered commenters will be listed in the monthly hearing folder on the commission’s website.
The Public Comments and Party Status Memo serves to provide clarification to parties to the commission rulemaking proceedings and all stakeholders who can or cannot provide public comments regarding a rulemaking with respect to party affiliation.
Written comments on any air quality issue are welcome and can be sent to: cdphe.aqcc@state.co.us
¡La comisión quiere escuchar sus comentarios!
Para realizar comentarios públicos orales durante una audiencia, deberá inscribirse para realizar comentarios públicos al registrarse para la audiencia (a través de Zoom). Si los cupos para la audiencia pública para comentarios se llenan, se escuchará a quienes se inscribieron primero. La inscripción cierra en la mañana de la reunión. Las personas registradas para comentar aparecerán en la carpeta de audiencias mensuales en el sitio web de la comisión.
El Memorando sobre comentarios públicos y condición de las partes sirve para brindar aclaraciones a las partes sobre los procesos de formulación de normas de la comisión y a todas las partes interesadas que pueden o no presentar comentarios públicos en relación con la formulación de normas, en función de su afiliación como parte.
Se aceptan comentarios por escrito sobre cualquier tema relacionado con la calidad del aire, que pueden enviarse a: cdphe.aqcc@state.co.us
