COLLECTION OF CHARGES 16.1 A Sector Association may request the consent of the Administrator to collect charges due from Operators to the Administrator in respect of facilities under the charging scheme. 16.2 If a Sector Association wishes to collect charges due from an Operator to the Administrator under the charging scheme, the Sector Association may serve a notice in writing on the Administrator by the last working day in February in the calendar year in which the charges fall due. 16.3 A notice served under Rule 16.2 must specify the facilities in respect of which the Sector Association intends to collect charges, being not fewer than 50% of the facilities covered by an umbrella agreement. 16.4 Following receipt of the notice, the Administrator must: 16.4.1 consent to the Sector Association collecting charges; or 16.4.2 refuse consent to the Sector Association collecting charges, giving reasons for the decision. 16.5 If the Administrator consents to the Sector Association collecting charges the Sector Association must: 16.5.1 itemise charges separately in any invoices that it issues in respect of charges; 16.5.2 collect and remit all charges collected to the Administrator without deduction or set off by the last working day in September in each year; 16.5.3 prepare an annual report to the Administrator by the last working day in October in the year in which it has collected charges setting out which Operators it has collected charges from and which Operators have failed to pay charges due to the Sector Association. 16.6 A Sector Association must not actively pursue any outstanding charges after the last working day in September in any year in which they fall due. If a Sector Association receives charges after this date the Sector Association must accept the payment and remit this to the Environment Agency along with information identifying the Operator making the payment. 16.7 If a Sector Association fails to comply with any of its obligations under this Rule the Administrator may serve a notice on the Sector Association that consent to the Sector Association continuing to collect charges is withdrawn at the expiry of 20 working days from the date of the notice.
