ANNEX A

IMPLEMENTING RULES AND REGULATIONS OF THE MODIFIED WASTEWATER CHARGE SYSTEM IN THE LAGUNA DE BAY REGION

Section 1. Objective

 To harmonize the LLDA’s Environmental User Fee System with the Wastewater Charge System of DENR under the Philippine Clean Water Act of 2004;

 Section 2. Definition of Terms

Abstracted Water – refers to all the water supply/supplies, intake(s) or sources(s) that is (are) used by an industrial or commercial or other establishment or entity in any process, operation, or activity resulting in the generation of water that is discarded or discharged. For industrial parks and/or similar entities operating common and/or centralized wastewater or sewage treatment plants into which wastewater or sewage generated by locators are discharged, abstracted water refers to the water supplied by such industrial park or similar entity for the use of its locators

Domestic Sewage – refers to water discharged after use for personal hygiene and sanitation or other household uses

Effluent – is a general term denoting any wastewater, partially or completely treated, or in its natural state or liquid waste flowing out through a pipe or a single outlet structure from a manufacturing/industrial plant or wastewater treatment plant

Effluent concentration in the wastewater charge formula – refers to the arithmetic mean of the actual effluent concentrations of priority pollutant parameter (e.g. BOD or TSS)

Priority Pollutant Parameter - refers to that parameter or aggregation of substances in the wastewater discharge that has the greatest potential for adverse environmental impacts or risks to public health and safety 

Section 3. Coverage

These guidelines shall apply to all establishments in the Laguna de Bay Region covered by the Wastewater Charge System. 

Section 4. Exemptions

The following activities, projects, installations are exempted from securing Discharge Permit: 

1. Single residential buildings and similar human occupancy structures that have twelve (12) cubic meters per day or less in total domestic sewage generation;
2. Dry industrial establishment that generates twelve (12) cubic meters or less of total domestic sewage per day or with maximum of 212 workers and with septic tanks; and
3. Industrial or commercial establishment interconnected to central wastewater or sewage treatment plant or facility.

Section 5. Discharge Permit 

The Authority shall require owners or operators of facilities that discharge any liquid wastes or regulated effluents pursuant to this Board Resolution to secure a permit to discharge. As such, any person shall file an application in two (2) copies using prescribed forms.  

The Discharge Permit shall be the legal authorization granted by the Authority to discharge wastewater: Provided, that the discharge permit shall specify among others, the quantity and quality of effluent that said facilities are allowed to discharge into a particular water body, compliance schedule and monitoring requirement. 

One (1) Discharge Permit shall be issued for one industry/establishment even if with multiple outlets or outfalls or points of discharge; provided that the source(s) of the multiple outlets or outfalls or points of discharge are from only (1) common project or facility in a contiguous geographical area. 

Section 6. Fees for Discharge Permit 

The Discharge Permit Fees shall comprise three (3) types of fees:

i.     Processing Fee

ii.    Fixed Fee

iii.    Variable Fee

Processing Fee 

Upon filing of application for a Discharge Permit, a processing fee in the amount of PhP5,000.00 shall be paid.

Schedule of Fixed Fees 

The fixed fee will cover the cost of program administration including but not limited to cost of inspection/sampling and cost of laboratory analysis. It will be dependent on volumetric rate of discharge per outlet or outfall or point of discharge and according to the following schedule:

Schedule of Variable Fee

The variable fee is based on the net waste load model prescribed pursuant to Chapter 2, article 2, section 13 of the Philippine Clean Water Act and Rule 13 of the DAO 2005-10.

The Variable Fee shall be calculated on the basis of only one (1) priority pollutant parameter and shall be calculated for each outlet or outfall or point of discharge.

While there is no limit for the maximum number of discharge outlets from the entity, establishment, factory, or other regulated source, the division of discharge streams into or among several outlets shall not result to qualification to Section 3, (exemption) of this Board Resolution.

However, net waste load shall be limited to industry/establishment who abstract water from surface water. If the source of water is from groundwater or water suppliers (district or service providers), the concentration of water intake shall be assumed as zero or negligible priority pollutant parameter.

Section 7. Selection of Priority Pollutant Parameter

For industrial or commercial wastewaters with high organic or biodegradable materials, the charging parameter is 5-day Biochemical Oxygen Demand (BOD₅) while for wastewaters with high inorganic or non-biodegradable materials the charging parameter is Total Suspended Solids (TSS). In the event that the wastewater discharge is a combination of organic and inorganic materials, BOD₅ shall be applied. Table 1 shall be used to select the Priority Pollutant Parameter (PPP).

Table 1 Selection of Priority Pollutant Parameter 

The average concentration of PPP in the effluent, C_f, shall be the arithmetic mean of the PPP concentration for the period (typically one year) for which the net waste load is calculated, expressed in mg/l (or g/m³), provided that the concentrations are all complying or non-complying with the effluent standards.

Section 8. Determination of Priority Pollutant Parameter Concentration in the Abstracted Water

Where there is only one (1) source of water supply, the average concentration of PPP in abstracted water source, Ca, shall be the arithmetic mean of the PPP concentrations in the single abstracted water source for the period for which the net waste load is calculated (typically one year) expressed in mg/l (or g/m³).

Where there are multiple (more than one) sources of water (abstracted water) used in the process, operation, or activity, that results in the generation of water that is discarded or discharged at an outlet or outfall or point of discharge, the arithmetic mean concentration of the priority pollutant parameter shall be determined from the abstracted water source with the best quality (lowest arithmetic mean value of the applicable priority pollutant parameter).

Section 9. Unit Rate of Charge 

The prevailing unit rate of charge of Php5.00/kg for complying and Php30.00/kg for non-complying industries shall be applied until such time as the proposed supplemental guidelines of DAO 2005-10 is approved. 

Section 10.  Repealing Clause

All orders, rules and regulations or parts thereof, which are inconsistent with any of the provisions of this Board Resolution are hereby repealed or modified accordingly. 

Section 11. Effectivity

This resolution shall take effect fifteen (15) days after publication in a newspaper of general circulation.

APPROVED  on March 22, 2007.
