Section 7103-144.0 - General Requirements

144.1 For the purpose of this section, sludge and septage are divided into three types as shown in the table below.

Sludge Type	Percent Solids
Liquid	Less than 15
Cake	15-35
Dried	Greater than 35

144.2 The Department may issue permits to transport sludge off-site if the Department approves of the equipment to be used, the operations plan, and the destination of the sludge.

144.3 Liquid sludge or septage can be pumped and transported by pipeline. If liquid sludge is transported by truck, rail, or barge, closed watertight vessels shall be used such as tank trucks and railroad tank cars or other vessels which can provide equivalent protection against spills and leakage.

144.4 Cake may be transported in watertight boxes, such as dump trucks properly sealed to prevent leaks, or cement type vehicles. Unless the applicant demonstrates equivalent protection against spills and leakage, when sludge cake is transported in dump trucks, the following standards shall be met:

144.4.1 The trucks shall be equipped with splash guards firmly attached horizontally at the front and rear of the trailer;

144.4.2 Each splash guard shall cover at least 25 percent of the trailer's open area; and

144.4.3 A minimum 2 feet of freeboard shall be maintained between the sludge and the top of the trailer unless the top of the trailer is completely sealed.

144.5 The Department may require certain cake sludges to be transported as liquid sludge.

144.6 Dried sludge may be transported in open boxes, such as dump trucks, which are properly sealed to prevent leakage. The trucks shall be covered with tarps or the equivalent.

144.7 All vehicles used to transport sludge or septage shall be operated and maintained so as to be in compliance with all state and federal regulations and not present a hazard to human health or the environment through unsafe vehicle conditions. The permittee is responsible for the operation and maintenance of all vehicles operated under the permit.

144.8 All transporters of sludge or septage shall submit to the Department a plan for the prevention, control, and cleanup of accidental discharges. No transportation permit will be issued until such a plan has been submitted to and approved by the Department.

144.9 All transporters shall at all times maintain commercial automobile liability insurance with a combined single limit of at least $100,000, and shall submit a Certificate of Insurance demonstrating compliance with this regulation. All persons subject to these regulations that were permitted to transport in Delaware before the adoption of this requirement shall be subject to the requirement upon renewal of their permit, or 90 days after adoption of the part, whichever is first.
