Check site class and monitoring budgets before expanding
Adding equipment to a small factory, coating operation or manufacturing business can affect environmental management as well as rent and electricity costs.
Using actual working hours or low downstream emissions to classify the site can leave class-change procedures, measurement contracts and environmental staffing outside the budget.
Applying the whole-site class to every outlet can also overstate monitoring costs.
This Korea-based calculator uses Korean 2026 law and KRW quotes.
It compares current plan A with the whole post-expansion plan B using the same pure calculation engine as the Korean page.
Unknown facts remain pending; results support authority review and comparable quote requests.
Separate generation, actual emissions and contracted items
Generation for classification
Decree Annex 1-3 uses dust, sulfur oxides (SOx) and nitrogen oxides (NOx) generated before pollution control.
Sum their annual quantities and exclude only confirmed reserve facilities under Enforcement Rule Article 42.
Downstream concentrations and post-control emissions serve a different purpose.
Items for measurement quotes
Required measurements are not limited to these three pollutants.
Confirm pollutants subject to Annex 8 emission limits, excluding fugitive dust, and any applicable exceptions.
Include a separate quote row for other required substances, such as hydrogen chloride, even though they do not appear in the three generation fields.
The result does not calculate emission charges or establish compliance with concentration limits.
Distinguish the purpose of the permit, amendments, emission factors, maximum fuel use and stack readings before transferring numbers into the ledger.
Build a facility-to-outlet ledger with evidence
- Name each facility and enter its verified dust, SOx and NOx rates in kg/h.
Enter a confirmed zero for an absent pollutant; blank means unknown.
- Create outlets O1–O5 and select the outlet connected to each facility.
Several facilities connected to the same outlet are summed for that outlet.
- Reserve exclusion needs evidence and confirmation.
A checkbox without verified reserve status cannot lower the generation total.
- Retain the calculation date, permit or installation statement, verified factors and maximum fuel use, and recognition documents.
This tool accepts hourly generation already established under Annex 10; it does not infer emission factors for every process.
Each plan supports up to 10 facilities, 5 outlets and 8 measurement items per outlet.
A facility split between several outlets, process recirculation or complex mixed ducts needs a verified allocation basis first.
Do not duplicate a facility into several rows and count the same generation twice.
Reserve exclusion from generation does not establish a monitoring exemption.
An outlet without connected non-reserve facilities is not automatically free: remove unnecessary empty outlet rows, or use a confirmed special schedule for a reserve-only outlet.
Use 24 × 365 unless intermittent operation is recognized
Facility generation (t/year) = (dust + SOx + NOx) kg/h × hours/day × days/year ÷ 1,000
The statutory default is 24 × 365 = 8,760 hours.
A desired shift pattern or internal working calendar does not establish an exception.
Article 44 covers facilities, such as heating boilers, that the competent environmental authority recognizes as operating only during certain times or periods.
An existing recognized facility uses previous-year average daily operating hours and annual operating days.
A newly installed recognized facility uses scheduled hours and days in its installation statement.
Record the existing/new basis and recognition evidence together.
Rates and hours accept up to six decimals; annual days must be an integer from 0 to 365.
Fixed-point integer arithmetic compares totals and thresholds before display rounding.
Near a threshold, examine the source ledger and class result together rather than interpreting a rounded display as the original value.
Site and outlet classes use different aggregation scopes
The boundaries are 80, 20, 10 and 2 t/year for both classifications, but the included facility groups differ.
Reaching a boundary moves the result to the larger class.
The displayed distance is the amount needed to reach that boundary, not an allowance that can be added while retaining the same class.
Classes 1–5 by annual pre-control generation, lower limits inclusive| Class | Lower t/year | Upper t/year |
|---|
| 1 | 80 inclusive | No upper limit |
| 2 | 20 inclusive | Below 80 |
| 3 | 10 inclusive | Below 20 |
| 4 | 2 inclusive | Below 10 |
| 5 | 0 inclusive | Below 2 |
Plan B must include all retained existing facilities and all new facilities.
Entering only the increase makes its scope inconsistent with A.
Copy A to B first, then adjust facilities, connected outlets, applicable items and quotes.
Basic monitoring schedules and annual budget factors
Annex 11 distinguishes automatic transmission to the stack remote-monitoring center and whether manual measurements cover downstream only or both upstream and downstream.
The table gives annual budget factors for outlet classes 1–5 before item-specific exceptions.
Annual monitoring budget factors; weekly and fortnightly figures are assumptions| Measurement mode | Class 1 | Class 2 | Class 3 | Class 4 | Class 5 |
|---|
| Non-TMS site | 53 | 24 | 6 | 2 | 2 |
| TMS site: manual items downstream | 27 | 12 | 6 | 2 | 2 |
| TMS site: manual items both sides | 12 | 6 | 4 | 2 | 2 |
Non-TMS schedules are at least weekly, twice monthly, every two months, once per half-year and once per half-year.
TMS downstream schedules are at least every two weeks, monthly, every two months and once per half-year for classes 4 and 5.
TMS both-side schedules are at least monthly, every two months, quarterly and once per half-year for classes 4 and 5.
The 53/27 factors use ceil(365/7) and ceil(365/14) for budgeting; actual dates must satisfy every required statutory period.
Apply hazardous, PAH, exemption and TMS rules per item
Separate item schedules
For non-TMS class 3–5 outlets, a specific hazardous pollutant at its Annex 8-2 threshold follows the twice-monthly route, budgeted as 24.
PAH has the separate once-per-half-year rule in Note 1-2.
A confirmed pollution-control-installation exemption follows at least annual monitoring under Note 2.
Only the corresponding TMS item
Normal automatic monitoring under Note 4 produces zero manual measurements for the corresponding item.
It does not set every other item to zero.
Do not select this route for equipment faults or unknown transmission status.
Fuel sulfur-analysis substitution, dust-only facilities, low-concentration reductions, voluntary agreements, testing-contractor requirements, first measurement periods, recognized low-NOx burners, official inspection substitution and island/disaster omissions have distinct conditions and periods.
For these cases, enter an authority-confirmed annual manual count, cycle, covered period and provision under the special route.
Hazardous-pollutant rules combined with TMS also require a confirmed special schedule rather than an automatically inferred stricter or reduced frequency.
Keep uncertain combinations unknown so that the final budget remains pending.
Use actual item quotes and separate common costs
Item annual cost = budget count × actual per-item unit quote
Total annual budget = all item annual costs + extra annual costs
Monthly reserve = total annual budget ÷ 12
No nationwide measurement tariff or market-average price is inserted automatically.
Enter whole-KRW outlays on a consistent basis for VAT, travel, sampling, analysis and both measurement sides.
For a visit covering several items, allocate travel charges without duplication or enter the common annual amount once.
Enter verified environmental staffing, TMS operation and calibration costs separately.
That field does not determine legal staffing qualifications or minimum headcount.
An unknown quote leaves the total pending while known costs remain a partial subtotal.
The input limit is KRW 1 billion per money field; monthly reserve is a simple saving reference, not a payment schedule.
Step-by-step use and saving the ledger
- Check the site scope and facility/outlet connections against permits, installation statements and drawings.
Do not confirm ordinary legal scope for an integrated-permit system without review.
- Enter all three hourly rates, reserve status, the time basis and evidence.
Verify authority recognition before using hours other than the statutory default.
- Select each outlet’s TMS route and enter every applicable item, rule and actual quote.
Document confirmed counts and covered periods for complex exceptions.
- Copy current plan A to full expansion plan B, update the entire retained/new inventory, then calculate.
Read whole-site and individual-outlet changes separately.
- Resolve pending items and save the TXT ledger.
Ask the authority about class changes, recognized hours and exceptions, then obtain comparable contractor quotes and actual measurement dates.
Worked example: the site changes class while outlets do not
Current plan A
O1 generates 0.5+0.2+0.3=1 kg/h, or 8.76 t/year.
O2 generates 0.1 kg/h, or 0.876 t/year.
The site total is 9.636 t/year, class 4, with 0.364 t to reach 10.
One ordinary item at O1 costs 2×100,000 KRW; the O2 item costs 2×80,000 KRW.
The annual budget is 360,000 KRW and the monthly reserve is 30,000 KRW, assuming confirmed extra costs of zero.
Full post-expansion plan B
O1 increases to 1.1 kg/h, giving 9.636 t/year; O2 stays at 0.876 t/year.
The total is 10.512 t/year, site class 3, with 9.488 t to reach 20.
O1 remains outlet class 4 and O2 remains outlet class 5.
Adding a threshold-level hazardous item at O1 costs 24×150,000=3,600,000 KRW.
The annual budget becomes 3,960,000 KRW and monthly reserve 330,000 KRW.
The annual cost difference is 3,600,000 KRW.
The generation increase is 0.876 t/year; the added measurement item is the direct cause of the cost increase in this example.
Do not assign class 3 schedules to every outlet simply because the site becomes class 3.
Names, rates and quotes are fictional calculation inputs rather than process emission factors or current market prices.
Use the comparison for expansion, leasing and renewal
Before ordering equipment
Add the new facility’s verified hourly generation and outlet connection to the existing inventory.
Check the distance to the next boundary and separately review amendment procedures and staffing costs.
Document anything still missing from the operating budget.
Before leasing a factory
Compare the existing permit with actual equipment and ducts rather than copying a class supplied by the landlord.
Verify location and installation-permit issues with the authority before translating assumptions into lease terms.
Before renewing a measurement contract
Compare the same item list, cycles, both-side scope and travel coverage.
Check for omitted new substances and expired reduction evidence.
This makes contract gaps visible beyond a simple unit-price comparison.
Reporting, records and limits
Article 52 sets half-year reporting deadlines of July 31 for the first half and January 31 next year for the second half.
Lawful electronic recording and retention under Article 36 can permit omission of separate submission; verify applicability.
Filters and sampling logs have a six-month retention rule from measurement.
Do not generalize that period to all environmental records.
Annual budget factors are not proof of completed measurements or compliance with timing requirements.
For a newly installed facility, Annex 11 Note 11 applies the first measurement from the following relevant period after startup.
Do not reduce a startup-year budget merely by multiplying by operating months.
Verify the actual class-change trigger, filing procedure, record format and deadline handling with the authority.
This is an ordinary-facility ledger and quote comparison.
It does not establish process-wide factors, integrated permits, location or installation approval, emission charges, concentration compliance or environmental personnel qualifications.
Edits invalidate previous results; replace unknown facts with verified inputs before relying on a final budget.
Frequently asked questions
Is generation the same as actual stack emissions?
No.
Classification uses dust, sulfur oxides and nitrogen oxides generated before pollution control.
Downstream stack readings or quantities after removal efficiency can understate this basis.
Obtain hourly rates established under Enforcement Rule Annex 10 and retain the evidence.
Can I use an eight-hour day and a five-day working week?
The default is 24 hours per day and 365 days per year.
Article 44 permits different hours or days only for facilities recognized by the authority as operating intermittently.
Existing facilities use previous-year average daily hours and annual operating days; new facilities use the installation statement.
Does a class 3 site have class 3 outlets everywhere?
No.
Site class sums the included facilities across the whole site.
Outlet measurement class sums facilities connected to that outlet.
A change in whole-site class does not itself change every outlet’s class, applicable item or exception.
Does TMS make every monitoring cost zero?
Only the corresponding normally automatically measured item receives the manual-measurement substitution.
Other items, equipment faults and hazardous-pollutant combinations require separate review.
Enter TMS operation, calibration and environmental staffing costs separately as extra annual costs.
How do hazardous pollutants and PAH differ?
At non-TMS sites, class 3–5 outlets emitting specific hazardous pollutants at Annex 8-2 thresholds generally follow at least twice-monthly measurements for the corresponding item.
PAH uses the separate once-per-half-year rule in Note 1-2.
For TMS, reduced frequencies or overlapping exceptions, obtain a confirmed schedule and enter its count, period and evidence under the special route.
Why is a weekly budget factor 53?
The tool uses ceil(365/7)=53 for full-year weekly budgeting and ceil(365/14)=27 for fortnightly budgeting.
These are budgeting assumptions rather than statutory annual counts.
Schedule actual dates within every required week, month, quarter or half-year instead of only reaching an annual total.
What happens when a quote is blank?
A missing required quote holds the total annual budget.
Only known monitoring costs appear in the partial subtotal.
Blank is different from a confirmed zero.
A normal TMS item with zero manual measurements needs no manual quote, but TMS operating costs remain separate.
What should I do with the result?
Save the TXT ledger for the environmental authority’s review of generation, class changes, intermittent-operation recognition and exceptions.
Then request item-specific quotes on the same cost basis.
The result is not an installation permit, emissions-compliance decision, staffing qualification or proof that measurements were performed.
