2. SCOPE

INTRODUCTION

Clackamas County Water Environment Services (“WES”) is seeking proposals from vendors to provide the supply of multiple chemicals and their delivery to three (3) separate locations on an as-needed basis. Multiple contracts may be awarded as a result of this RFQ. If multiple contracts are awarded, the number of contracts awarded will be the sole determination of the County based on need.

Please direct all technical/specification or procurement process questions to the representative indicated in the Notice of Request for Proposals and note the communication restrictions outlined in Section 2.19.

BACKGROUND

Clackamas County Water Environment Services (WES) provides wastewater management services to over 150,000 people in Clackamas County, Oregon, and operates multiple wastewater treatment plants, three of which produce biosolids.

WES includes the Kellogg Creek WRRF (formerly known as the Kellogg Creek WPCP) located in Milwaukie, serving Happy Valley, unincorporated North Clackamas County and wholesale customers in the City of Milwaukie and Johnson City, as well as the Hoodland Sewage Treatment Plant (STP), located in Welches serving the Mt. Hood Recreational Corridor of Clackamas County. The Boring STP serves the community of Boring.

Clackamas County WES operates all facilities including a biosolids management program that produces a Class B biosolids product. Biosolids processed in the plants’ digesters are currently hauled and land applied on agricultural lands in Clackamas and Sherman Counties.

SCOPE OF WORK

The WES operated treatment facilities utilize various chemicals to ensure regulatory compliance requirements. Daily consumption varies upon changes in flow, water quality, and process control demands.

In order to fulfill the needs of the different plant locations, it is the intent of the District to award a contract to multiple vendors.

A. General Requirements

• Marking: Each shipment shall be identified as to product, grade, net weight, name of manufacturer and brand name.

• Removal of Unsatisfactory Materials: If the material (chemical) does not meet the requirements of the appropriate WES Standard, or is not satisfactory to the WES project manager (or appointed representative) the vendor shall remove the material from the premises at the purchaser’s request and replace it with a like amount of satisfactory material, or a price adjustment may be agreed upon between the purchaser and the vendor.

• Vendors and chemicals shall comply with all applicable rules and regulations of the State of Oregon and all other authorities having jurisdiction. Deliveries will be within a reasonable time, relative to the placement of an order. Expected response from date of order is five (5) days, however emergency situations may require same day or next day delivery.

• Delivery times shall be coordinated with WES, or a WES representative, at the time of placing an order.

• Data Sheets shall be provided for all received chemicals.

B. Chemical Descriptions

Chemical Description Estimated Annual Consumption Sodium Bisulfite 38% - 4,000 gallons per delivery 550,000 lbs Hydrated Lime 15 tons per delivery 450 tons Sodium Bicarbonate 50 lbs bags; 2,450lbs/pallet 2,500 lbs Sodium Hydroxide 20% - 3,000 gallons per delivery 3,000 gallons Citric Acid 50% solution – 2,800 lb tote 8,400 lbs Phosphoric Acid 75% in 700 lb Drums, 2,800 lbs Caustic Soda 50 lbs bags; 2,450lbs/pallet 2,450 lbs

Sodium Hypochlorite Solution 12.5% Filtered 200,000 gallons Calcium Carbonate AquaCal SS70 65% solids content 610 tons Calcium Carbonate AqualCal 150 75% solids content 610 tons

C. Chemical Specifications The list below specifies chemicals used, a brief description of the purpose, and the chemical composition of each. The expectation for each chemical is that it will meet the specifications provided and no alternative chemicals will be accepted.

• Sodium Bisulfite

Sodium Bisulfite is used as a dichlorination agent at the Tri-City facility. The Tri-City facility splits flow after a shared primary treatment process. The controlled portion of flow that enters the Conventional Activated Sludge, (CAS) side of treatment is currently disinfected using Sodium Hypochlorite. Tri-City, Hoodland, and Kellogg currently use Sodium Bisulfite for dichlorination post disinfection.

Chemical Composition Minimum (% by weight) CAS Number Water 60-90 7732-18-5 Sodium Bisulfite 38% 7631-90-5 Sodium Sulfite <1.0 7757-83-7 Sodium Sulfate <1.0 7757-82-6

• Hydrated Lime

Hydrated Lime is currently used to control pH on the Membrane Bio Reactor (MBR) side of treatment.

The effectiveness of lime is to control pH and ultimately allow us to maintain the needed alkalinity of greater than 100 mg/L within treatment process. Alkalinity is tested daily and lime dose rates adjusted to meet the target goal of 100 mg/L.

Calcium Hydroxide >90 1305-62-0 Magnesium Oxide <3 1309-48-4 Calcium Carbonate <3 1317-65-3 Crystalline Silica <2 14808-60-7

• Sodium Bicarbonate Sodium Bicarbonate is used for pH control within the digester system. Digester loadings, temperature and/or mixing complications can all result in an unhealthy digester environment. During such events the digester gas producing organisms, or methanogens, slow down and gas production often decreases significantly, sometimes resulting in a gas quality that can no longer be reused within the gas utilization system. Acid/Alkalinity analysis is run twice/week, and Sodium Bicarbonate dosing is triggered once the ratio hits 0.0300 mg/L or if the trend is swinging upward quickly.

Sodium Bicarbonate 100 144-55-8

• Sodium Hydroxide

Sodium Hydroxide is used as a scrubbing agent used as part of the chemical building scrubber system.

The chemical scrubber is designed to collect and remove chlorine gas from the storage room in the event of a chlorine release greater than 3.0 ppm chlorine gas. Chemical orders are triggered either by tank level on the scrubber vessel hydrometer results which verify concentration +/- 1%.

Sodium Hydroxide 20% 1310-73-2 Water 80% 7732-18-5

• Citric Acid

Citric Acid is used as a cleaning agent during the membrane recovery clean in the MBR system. Over time the membrane begins to collect inorganic substances on the membrane surface. The membranes are soaked for 18 hours in a Citric Acid bath. Citric Acid softens the inorganic buildup allowing for removal and ultimately a more efficient treatment process.

Citric Acid 49-51% 77-92-2 Water Balance 7732-18-5

• Caustic Soda Caustic Soda has multiple uses ranging from odor control, degrading fats, oils, and grease and for pH adjustment.

For pH control, caustic soda allows for quick rapid adjustments of pH. The alkaline nature of caustic soda also benefits the breakdown of fats and greases and is used to clean conveyance piping and/or valves. Caustic soda can also be used as a cleaning agent to remove organic foulants from pumps, pipes and tanks.

Sodium 57% 7440-23-5 Hydrogen 40% 1333-74-0 Oxygen 3% 7782-44-7

• Sodium Hypochlorite

Sodium Hypochlorite: Used as an oxidizer to provide pathogen reduction control. Daily consumption varies upon changes in flow and water quality. The strength of our sodium hypochlorite is measured in residual ppm and decomposes over time. Product freshness and purity are critical to achieve expected results. For this reason, we are soliciting quotes for a filtered low salt product. By using a filtered low salt product, we can ensure a better quality and much more stable product.

Chemical Composition Minimum (% by weight) Maximum (% by weight) Sodium Hypochlorite 12.5 % 15.60 Sodium Chloride 2.5 % 6.00 Sodium Hydroxide 0.1 % 2.0 Sodium Carbonate 0.0 % 0.5 Inorganic Salt of Iron 0.0 % 0.5 mg/L (0.5 ppm) Inorganic Salt of Copper 0.0 % 0.05 mg/L (0.05 ppm) Inorganic Salt of Nickel 0.0 % 0.05 mg/L (0.05 ppm)

• Calcium Carbonate

Calcium Carbonate is an alternative chemical that can be used to control pH on the Membrane Bio Reactor, (MBR) side of treatment. The effectiveness of calcium carbonate is to maintain the needed alkalinity of greater than 80 mg/L within treatment process and ultimately allow for control of pH. Alkalinity is tested daily and lime dose rates adjusted to meet the target goal of 80 mg/L.

Microna AquaCal SS70

Chemical Composition Minimum (% of Dry Material) CAS Number Calcium Carbonate 98.5% 471-34-1 Magnesium Carbonate 1.4% 546-93-0 Acid 0.1% 7647-01-0

Microna AquaCal 150

Chemical Composition Minimum (% of Dry Material) CAS Number Calcium Carbonate 98% 471-34-1 Magnesium Carbonate 1% 546-93-0 Acid .1% 7647-01-0

• Phosphoric Acid

Phosphoric Acid is used in the cleaning of the Ultraviolet disinfection system at the Kellogg Creek WRRF, it is used to clean mineral scale, inorganics and organics from the quartz sleeves. They are bathed in the acid solution for roughly 45 minutes.

Phosphoric Acid 75% 7664-38-2 Water Balance 7732-18-5
