### ID **No. EPA-HQ-RCRA-200s..0329**  **Dear Sir**  **or Madam:**  **These comments**  **are submitted**  **by the**  **National Association**  **of Clean**  **Water Agencies**  

### ("NACWA") **in response**  **to the United**  **States** 

### Environmental **Protection Agency's**  **("EPA's"»)anuary 2,**  **2009 request**  **for public**  **comments on**  **the meaning**  **of "solid**  **waste" under**  **the Resource**  **Conservation and**  **Recovery Act**  **("RCM") published**  **at 74**  **Fed. Reg.**  **41-61. NACWA**  **asks that**  **EPA clarify**  **in its**  **upcoming rule** **making that**  **"solid waste"**  **does not**  **include the**  **sewage sludge**  **(biosolids) processed**  **at Publicly**  **Owned Treatment**  **Works ("POT'X's")**  **that are**  **the "solid and**  **dissolved materials in**  **domestic sewage"**  **that Congress**  **expressly exempts**  **from its**  **definition of**  **solid waste**  **at 42**  **U.S.c.** 

## § **6903(27). The**  **solid waste definition**  **rule presents**  **an opportunity**  **to clarify**  **and codify**  **that the**  **statutory Domestic**  **Sewage Exclusion**  **applies to**  **the sewage**  **sludge extracted**  **from domestic**  **sewage and**  **combusted or**  **land applied.**  **Express exclusion**  **of POTW**  **sewage sludge**  **from the**  **definition of**  **solid waste**  **is consistent**  **with NACWA's**  **position that sewage**  **sludge incinerators**  **("SSIs") should**  **be regulated**  **under Section**  **112 instead**  **of Section**  **129 of**  **the Clean**  **Air Act**  **("CAA"). NACWA**  **represents the**  **interests of** **nearly three**  **hundred of**  **chI" nation's**  **POTWs, which**  **collectively serve**  **the majority**  **of the**  **sewered population**  **in the**  **United States.**  **For over**  **thirty-five years,**  **NACWA has**  **maintained a**  **leadership role**  **in legal**  **and policy**  **issues affecting**  **dean water**  **agencies, and has**  **been at**  **the forefront**  **of the**  **development and**  **implementation of**  **scientifically-based, technically-sound,**  **and cost-effective**  **environmental programs**  **for protecting**  **public and**  **ecosystem health.**  **Congress' Domestic**  **Sewage Exclusion**  **recognizes the**  **unique function**  **and purpose**  **of**
