Declaring what left the plant
Once a year twelve months of scattered data must become a figure somebody signs. That somebody is you.
Periodically a declaration must be filed: what was consumed, emitted, managed, produced. **You generate none of that data** — the plant generates it, different equipment and systems collect it, and some of it comes from a third party. Your job is to gather it, reconcile it and sign a figure that from that moment is the official version of what happened.
Where each number you sign comes from
| The figure | Who generates it | What backs it |
|---|---|---|
| Own readings | Your equipment | The record, if retained |
| Analyses | A laboratory | Their report, with its date |
| Removals | An external contractor | **Their receipt, which can be late** |
| **Estimates** | **You** | **The basis, if it was written down** |
Important
**What must be defensible is not the declared figure: it is how it was reached.** A later review rarely disputes the number itself; it disputes where it came from, what was included, what was estimated and on what basis. If the calculation lives in a spreadsheet made by somebody who has left, with unexplained columns, the figure can be perfectly correct and still be indefensible.
What turns the declaration into a formality
- 1
Collect during the year, not at the end
What is asked for in January is scattered across twelve months of places.
- 2
Store the evidence beside the figure
The report, the receipt and the reading, not just the number.
- 3
Write down the basis for anything estimated
At the time, while someone remembers why it was estimated that way.
- 4
And keep the declaration with its evidence
It is reviewed years later, not the following week.
Watch out
What most delays this position is **the figure that depends on a third party**: the receipt the contractor has not sent, the missing analysis, the laboratory certificate. It gets chased in January, with the deadline looming, and arrives when it arrives. Asking for it during the year —as it is generated, not at the end— is the only way to stop the deadline depending on somebody else's diary.
Worth knowing
What declarations are mandatory for your installation, what data they include, what calculation or estimation methods are acceptable and how long the supporting evidence must be kept **is determined by the applicable rules and your authorisation, and settled by your adviser or the competent body**. Here we cover the organisational part: how to gather the year during the year and be able to explain the figure afterwards.
›Do I only keep the filed declaration?
Also what backs it. That is what gets reviewed later.
›How do I justify an estimate?
By writing the basis when it is applied, not when it is questioned.
›What if a third party is late with their part?
Which is why it pays to request it during the year, with automatic chasing.
A real case
The situation
In January twelve months of scattered data must be gathered.
What you do
- Collects and files each figure as it is generated
What you get
The declaration is prepared without an annual campaign.
The situation
An external contractor's receipt is missing.
What you do
- Requests and chases automatically through the year
What you get
Third-party data arrives before the deadline.
The situation
A review asks where a figure came from.
What you do
- Stores the evidence beside the declared figure
What you get
The number's origin can be shown.
The situation
The calculation lives in a spreadsheet by someone who has left.
What you do
- Keeps the written basis with the file
What you get
The figure stops depending on one person.
The situation
A figure is estimated and nobody notes why.
What you do
- Allows recording the basis at the moment
What you get
The estimate is explicable years later.
The situation
The declaration is filed and no copy with its evidence is kept.
What you do
- Keeps what was filed and what supported it
What you get
The later review has something to answer with.
