CHAPTER 40. EROSION AND SEDIMENTATION CONTROL


(a) Legislative findings. — The General Assembly finds that erosion and sedimentation continue to present serious problems throughout the State, and that the removal of a stable ground cover in conjunction with the decrease in the infiltration capability of soils resulting from the creation of additional impervious areas such as roads and parking lots has accelerated the process of soil erosion and sediment deposition resulting in pollution of the waters of the State. This damages domestic, agricultural, industrial, recreational, fish and wildlife and other resource uses. The General Assembly further finds that accelerated stormwater runoff increases flood flows and velocities, contributes to erosion, sedimentation, and degradation of water quality, overtaxes the carrying capacity of streams and storm sewers, greatly increases the costs of public facilities in carrying and controlling stormwater, undermines flood plain management and flood control efforts in downstream communities, reduces groundwater recharge, and threatens public health, welfare, and safety.

(b) Statement of policy. — In consideration of these legislative findings, it is declared to be the policy of this chapter to strengthen and extend the present erosion and sediment control activities and programs of this State for both rural and urban lands and to provide for control and management of stormwater runoff consistent with sound water and land use practices. These activities will reduce to the extent possible any adverse effects of stormwater runoff on the water and lands of the State. This policy, to be carried out by establishing and implementing by the Department of Natural Resources and Environmental Control, hereinafter referred to as the "Department," in cooperation with conservation districts, counties, municipalities and other local governments and subdivisions of this State, and other public and private entities, a statewide comprehensive and coordinated erosion and sediment control and stormwater management program to conserve and protect land, water, air and other resources of the State. This program shall be consistent with, and coordinated with other environmental programs implemented by the Department such as wetlands protection and groundwater protection.

(f) In any situation where a certified construction reviewer's approval is being suspended or revoked, an opportunity for hearing before the Secretary or the Secretary's designee shall be provided. During any suspension or revocation, the certified construction reviewer shall not be allowed to provide construction reviews pursuant to this chapter.

(g) The failure to assign a departmental approved certified construction reviewer to a land disturbing activity, when required by the approved plan, will place that project in violation of this chapter and result in appropriate administrative and/or enforcement action.

67 Del. Laws, c. 234, § 1; 70 Del. Laws, c. 186, § 1.;

After July 1, 1991, any applicant seeking sediment and stormwater plan approval shall certify to the appropriate approval agency that all responsible personnel involved in the construction project will have a certificate of attendance at a departmentally sponsored or approved training course for the control of sediment and stormwater before initiation of any land disturbing activity. The certificate of attendance shall be valid until the Department notifies the individual or announces in local newspapers that recertification is required due to a change in course content.

67 Del. Laws, c. 234, § 1.;

(a) Any person who violates any rule, regulation, order, condition imposed in an approved plan or other provision of this chapter shall be fined not less than $200 or more than $2,000 for each offense. Each day that the violation continues shall constitute a separate offense. The Justice of the Peace Courts shall have jurisdiction of offenses brought under this subsection.

(b) Any person who intentionally, knowingly, and after written notice to comply, violates or refuses to comply with any notice issued pursuant to § 4012 of this title shall be fined not less than $500 or more than $10,000 for each offense. Each day the violation continues shall constitute a separate offense. The Superior Court shall have jurisdiction of offenses brought under this subsection.

61 Del. Laws, c. 522, § 1; 66 Del. Laws, c. 196, §§ 1, 2; 67 Del. Laws, c. 234, § 1; 69 Del. Laws, c. 349, § 1.;

The Court of Chancery shall have jurisdiction to enjoin violations of this chapter. The appropriate program element authority, the Department or any aggrieved person who suffers damage or is likely to suffer damage because of a violation or threatened violation of this chapter may apply to the Chancery Court for injunctive relief. Among any other appropriate forms of relief, the Chancery Court may direct the violator to restore the affected land or water impacted area to its original condition.

61 Del. Laws, c. 522, § 1; 67 Del. Laws, c. 234, § 1.;

(a)(1) Offset provisions. — The Department may require an offset as an alternative to full or partial compliance with the resource protection event requirements as provided in subsection (e) of this section and § 4006(d)(1)a. of this title.

(2) Offset requirements are subject to departmental review and approval and to the public notice requirements of § 6004 of this title.

(3) The Department may develop and publish procedures for determining offset options in a technical document supplement to this section.

(b)(1) Standard plans. — The Department may develop criteria for standard plans when a detailed plan is deemed not necessary. Project types that may qualify for a standard plan include, individual parcel construction or improvements, tax ditch maintenance, minor linear disturbances, stormwater facility maintenance, agricultural structure construction, or other activities approved by the Department.

(2) All standard plans must contain standard conditions for construction site stormwater management and may contain standard conditions for post construction stormwater management.

(3) The inclusion of an activity in the standard plan classification does not exclude that activity from the requirements of this chapter. Rather, the standard plan precludes that activity from the necessity of a detailed plan review for a qualifying project.

(4) Failure to implement control practices under conditions included in the standard plan may necessitate appropriate enforcement action under this chapter.

(5) A detailed plan may be required for a site that would otherwise meet standard plan criteria as deemed appropriate by the Department or delegated agency on a case-by-case basis.

(c) The Department recognizes the benefits of redevelopment. The requirements under this section are intended to encourage redevelopment while establishing compliance criteria that meet the overall goals and intent of this chapter.

(d) In the case of development of a contaminated or brownfield site, a remediation plan approved by the Department will meet the stormwater management goals and the intent of these regulations with prior consent and subsequent approval by the Department. Compliance with the resource protection event criteria under § 4006(d)(1)a. of this title must be accomplished to the maximum extent practicable for development of a contaminated or brownfield site in instances where the Site Investigation and Remediation Section (SIRS) does not apply infiltration restrictions.

(1) Redevelopment of a contaminated or brownfield site resulting in a reduction of impervious surface where no known drainage issues exist or will be created must be considered in compliance with this section.

(2) Redevelopment of a contaminated or brownfield site resulting in an increase in impervious surface where no known drainage issues exist or will be created must employ runoff reduction practices to achieve compliance with the RPv with a 30% reduction in the required volume of runoff to be treated.

(e) Compliance with the resource protection event criteria under § 4006(d)(1)a. of this title must be accomplished to the maximum extent practicable for redevelopment projects through one of the following:

(1) Redevelopment resulting in less than 1 acre of disturbed area must adhere to subsection (b) of this section. Projects that cannot adhere to subsection (b) of this section must comply with paragraph of (e)(2) or (e)(3) of this section, as applicable.

(2) Redevelopment on sites with stormwater management systems designed and functioning in accordance with the Delaware Sediment and Stormwater Regulations first promulgated on January 23, 1991:

a. Redevelopment resulting in a reduction of impervious surface where no known drainage issues exist or will be created and there are no outstanding stormwater-related maintenance issues to be resolved or addressed must be considered in compliance with this section.

b. Redevelopment resulting in an increase in impervious surface where no known drainage issues exist or will be created must employ runoff reduction practices to achieve an equivalent open space in good condition for the increased impervious surface.

(3) Redevelopment on sites without stormwater management systems designed and functioning in accordance with the Delaware Sediment and Stormwater Regulations first promulgated on January 23, 1991:

a. Redevelopment resulting in a reduction of 15% or greater in impervious surface must be considered in compliance with these Regulations.

b. Redevelopment resulting in a reduction of less than 15% impervious surface where no known drainage issues exist or will be created must employ runoff reduction practices to achieve an equivalent 15% reduction in effective imperviousness.

c. Redevelopment resulting in an increase in impervious surface shall employ runoff reduction practices to achieve an equivalent 15% reduction in effective imperviousness for existing impervious areas and an equivalent open space in good condition for an area equivalent to the increase in impervious surface.

(f) If the minimum runoff reduction requirements are not met, an offset under subsection (a) of this section must be provided for the portion of the RPv that does not meet the minimum runoff reduction requirements under § 4006(d)(1)a., of this title.

(1) Any redevelopment project that increases the rate, volume, or duration of flow to a new or existing point of discharge during the conveyance event must be managed in accordance with reference BMP's, exclusive of volume requirements.

(2) Any redevelopment project that increases the rate, volume, or duration of flow to a new or existing point of discharge during the Flooding Event must comply be managed in accordance with reference BMP's, exclusive of volume requirements.
