23 High flow block—determination of volume discharge limit

(1) The volume discharge limit for an authorised discharge point, in relation to a high flow block, is to be determined in accordance with the following steps:

Step 1: Determine the number of credits available for use

The number of credits available for use is to be determined as follows:

Where:

E is the number of credits available for use.

Cr is the number of credits assigned to the authorised discharge point in relation to the block at the start of the discharge (as entered in the Credit Register), being credits that are in force, and excluding any credits forfeited under this Regulation or that are excluded under Part 4A or 5.

Note—

Parts 4–5 explain credit holdings, assignment of credits to an authorised discharge point and trading in credits. Under Parts 4A and 5, a credit that is assigned or transferred in contravention of the Regulation cannot be counted towards the volume discharge limit for an authorised discharge point.

D is the sector credit discount factor for the block at the start of the discharge.

Step 2: Determine the salt discharge limit for the authorised discharge point

The salt discharge limit for the authorised discharge point is to be determined as follows:

Where:

L is the salt discharge limit for the authorised discharge point (in tonnes).

T is the total allowable discharge for the block (in tonnes) at the start of the discharge.

E is the number of credits available for use, being the amount determined in step 1 rounded down to the nearest whole number.

Step 3: Calculate the salt concentration of the water to be discharged

The salt concentration of the water to be discharged is to be calculated as follows:

Where:

C is the salt concentration of the water to be discharged from the authorised discharge point, measured in tonnes per megalitre.
