3-4 waste types, sources AND CLASSIFICATIONS The following three sections describe types of waste applicable to ISS, sources of waste on ISS, and waste classifications. National Aeronautics and Space Administration (NASA) is responsible for managing all United States On-orbit Segment (USOS) waste including waste generated by the Canadian Space Agency (CSA), European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), and (NASA). Roscosmos [Russian Segment (RS)] is responsible for managing RS waste.

types of waste In this document the term “waste” is synonymous with the term “trash”. Waste is comprised of common (daily waste) and non-common waste that are to be removed from the ISS and are not required to be returned for any purpose. Non-common waste requires a Waste Manifest Request (WMR).

common waste Common waste is often referred to operationally as crew daily waste or common trash. Common waste includes ISS waste that is generated by the crew in day-to-day operations/living, and not from specific systems/utilization tasks. It consists principally of wet/dry used or expired consumables, non-refurbishable crew provisions, hygiene, and food packaging waste. Each segment bears the responsibility for the stowage and disposal of the total waste proportional to the share of their crewmembers. See Appendix G for the list of approved common waste.

1.1.1 Non-common waste

hardware waste Hardware waste includes any used, defective, no longer needed, or expired hardware. Hardware waste may be replaced at known rates for items with limited life, or after an unexpected failure. Hardware waste is assigned to the USOS system or payload generated waste. USOS is responsible for the collection, stowage, and disposal of waste from the use of their modules of the ISS.

Foam Foam is used to protect cargo on an ISS launch vehicle for delivery to or removal of hardware from ISS that is not required on orbit for other planned uses. The USOS and RS whose launch vehicle delivered the launch foam to the ISS is responsible for the collection, stowage and disposal of packaging waste generated.

SOURCES OF WASTE

Sources of ISS waste include the following:

Waste classifications and Categories <TBD 3-1> Waste hazards There are several types of waste hazards, including the following: liquid, magnetic battery, biological/biomedical, sharps, chemical, radioactive, and toxic waste.

Liquids Liquids that do not present a biological, chemical, or radioactive hazard must have a minimum of 2 levels of containment and be in a configuration that would not present a hazard during depress. Liquids that also present a biological, chemical, or radioactive hazard must also meet the containment requirements for the other hazard(s) identified.

1.1.1.1 Magnets

Items that contain permanent magnets (ex: headphones, hard drives, fans) must be tested in order to determine if they meet Category 1 criteria. For items that have a magnetic field strength above Category 1 limits, special packing and/or specific disposal locations on the disposal vehicle may be required.

BATTERY WASTE

Crewmembers will inspect batteries for damage prior to disposal in a Ziploc bag. If damaged, batteries will have both terminals taped. All 9 Volt (V) batteries will have both terminals taped.

BIOLOGICAL/BIOMEDICAL WASTE

Biological/Biomedical waste must be properly contained based on its bio-safety level. The biosafety level for any waste which poses a significant health threat to exposed personnel is identified by categories defined in JSC 63828, Biosafety Review Board Operations and Requirements Document. The designated biosafety level for a given waste item will determine the number of levels of containment that are required to contain the waste item(s).

SHARPS WASTE

All sharps waste is placed in an approved container for disposal. Sharps containers must be puncture resistant, leak proof, and sealable.

CHEMICAL WASTE

Individual chemical waste types (based on chemical properties and not on hazard levels) must be stowed for disposal in separate sealable waste containers. A second level of containment may be required on each chemical waste container when attempting to stow multiple chemical waste containers in the same larger size container; unless the appropriate safety review panel certifies that multiple chemical waste containers are compatible when stored in proximity to one another.

Chemical waste may also be toxic and pose a significant health threat to exposed personnel. The degree of the potential threat is identified by five toxicity codes defined in JSC 26895, Guidelines for Assessing the Toxic Hazard of Spacecraft Chemicals and Test Materials, which also identifies the number of levels of containment required for a given toxicity code.

RADIOACTIVE WASTE

Radioactive waste is packaged, labeled, and handled in accordance with requirements established by the Kennedy Space Center (KSC) Radiation Protection Officer/Johnson Space Center (JSC) Radiation Health Office and approved by the appropriate safety review panel. An assessment for these hazards will be made on a case-by-case basis.

The NASA Chief Radiation Safety Officer must evaluate any waste that is identified as a radiation emitter prior to disposal on an expendable vehicle. For US hardware/ payloads, JSC Form 44, Ionizing Radiation Source Data Sheet - Space Flight Hardware and Applications, is required to be submitted in order to define radioactive material and procedures (labeling, isolation, removal, etc.). This form is part of the Safety Data Package.

According to the Nuclear Regulatory Commission (NRC), the container for urine may be disposed if the effluent concentration of the radioactive waste does not exceed the concentration provided by NRC. The limiting concentration varies from 10^-6 to 10^-3 Curie (Ci)/milliliter (ml), depending on the type of the radioactive material, where 1 Ci is equal to 3.7 x 1010 disintegrations per second. The waste can be burned once the effluent concentration is below the limit.

Disposal of radioactive waste on Progress will be evaluated on a case-by-case basis.

Table 3.3-1 WASTE Hazards CLASSIFICATION

waste Categories Waste is classified for disposal in accordance with SSP 30599, Safety Review Process. Form ISS OE 907 may be used as a checklist to determine whether items meet the requirements to be classified as Category 1 and Category 2. The category of the waste will determine what safety paperwork is required.

Category 1 Category 1 items are hardware with only standard hazards and meet all of the constraints listed on ISS-OE-907, Flight Certification Form (Form-907). (Standard hazards are defined on ISS Form 1298.) Hardware owners are responsible for confirming their disposal items are considered category 1 and have not had any anomalies. If the item does not already have an ISS-OE-906, Multilateral Category 1 Constraint Form (Form 906) approved for disposal, the hardware provider is responsible for providing safety with form 906 including a concise description of the item (what it is, how it works, what it is made of, and its current configuration/status) and confirmation that the item meets category 1 criteria. It is not required to issue certificates or re-flight letters for category 1 cargo disposed of on Russian vehicles (Progress and Soyuz). It is sufficient to issue a list of the cargo for a specific flight signed by NASA safety (or IP safety for their cargo).e-z disposal waste The ISS E-Z Disposal process list is designed to alleviate the need to implement and process individual WMRs for the disposal of safe and commonly used items. The E-Z Disposal List is a coordinated list approved by NASA and RS Safety for certain small category 1 items with negligible size and mass. This list is posted on the Waste Management website. https://iss-www.jsc.nasa.gov/nwo/mio/cargo/wm/web/index.shtml Category 2 Category 2 hardware does not meet one or more of the constraints in JSC Form 907. Category 2 items are more hazardous pieces of hardware with unique hazards, or controls. A safety certificate (JSC Form 906) and hazard reports for those constraints that are not met are required to be submitted to Safety. The safety certificate must include a detailed hardware description including what the hardware is, how it works, what it is made of, its current status/configuration and any information pertinent to the JSC Form 907 constraints it does not meet. For battery descriptions, the chemistry, voltage and capacity must be listed explicitly. For toxic substances, the toxicity level must be listed explicitly. The hardware item’s project manager must sign as the project manager before Safety can obtain the other two signatures. Category 2 items which have been previously certified for transportation on a Russian vehicle and have not changed in status /configuration on-orbit, qualify as re-flight items and require a re-flight letter only.

Waste Containment and containers Containment describes packaging that prevents the crew or vehicle from being exposed to a hazard per SSP 50021, Safety Requirements Document, requirements. Not all containers that are certified to hold waste for storage and disposal qualify as a level of containment, particularly if they do not seal. While containers may be certified to have various types of waste placed in them such as dry or wet, hazardous or non-hazardous, urine, solid waste, or a combination thereof, the requirements for containment must also be met separately for hazardous waste. For example, a Jettison Stowage Bag (JSB) or Cargo Transfer Bag (CTB) may be used as a container to gather, stow or dispose of hazardous waste that is already appropriately contained. However, JSBs or CTBs do not qualify as a level of containment to protect the crew from the hazardous material. Some packaging may only be approved for use as containment on a case-by-case basis.

Waste containers Waste container hardware descriptions are located in Appendix D. Standard waste containers have been defined and are made available for on‑orbit use and disposal based upon standard waste generation rates. The complement of standard waste container hardware accommodates both planned and off-nominal operations.

Hardware and payload providers are responsible for estimating the mass/volume of their waste and verifying that the waste they generate is accommodated by the crew standard waste containers.

If a new container is required, the hardware/payload provider has the responsibility to ensure that unique containers are certified for use in the ISS and disposal on any vehicle. They must also ensure that sufficient quantities are fabricated to support crew operations.

waste container usage Table 4.1.1-1, Waste Container Usage, summarizes the types and general use of current waste hardware. Special handling requirements for waste hazards are documented in Section 3.3.1. Crew common waste may be stowed in containers listed in Table 4.1.1-1. Waste from hardware waste and payloads are evaluated on a case by case basis.

waste container Vehicle CERTIFICATION Table 4.1.2-1, Waste Container Vehicle Certification, lists the material certification status of the current hardware for launch, return, and disposal in the available ISS transportation vehicles and cargo carriers. Certification for this table implies approval of the use of the containers identified in the table for use on the vehicles for disposal by the vehicle owner.

RS uses Progress as their disposal vehicle. USOS uses Cygnus and HTV as their disposal vehicle. While trash can be returned on a RS Soyuz or a USOS Dragon (Space-X), it is not standard practice to use a return vehicle for trash.

4-3 waste management Planning and responsibilities Waste management responsibilities are spread among multiple disciplines and organizations. This section describes four areas of waste management responsibility: safety and handling; waste stowage; crew training; and increment disposal planning.

Segment roles and RESPONSIBILITIES The USOS is responsible for: USOS waste planning, stowage, and integration; USOS waste vehicle loading; and USOS waste safety certification.

The Russian Segment (Roscosmos/RSC-E) is responsible for RS Waste Planning, Stowage, and Integration (WPSI), RS waste pre-gather operations, Russian Segment roles and waste vehicle loading, Russian Segment waste safety certification.

USOS Roles and responsibilities The USOS participants include NASA, ESA, JAXA, and CSA.

NASA Roles and Responsibilities Waste planning, stowage, and Disposal Vehicle integration Specific breakdowns of internal NASA roles and responsibilities will be listed in a later section. NASA is responsible for coordinating USOS common waste, NASA non-common waste, stowage, and integration.

NASA waste, stowage, and integration is conducted via the WMR process, Trash/Waste Integration Group (TWIG) meetings, and chit reviews of USOS disposal lists. NASA is the lead for TWIG meetings and USOS disposal list coordination NASA is responsible for coordinating USOS common and USOS non-common trash for disposal on CRS (Cygnus, Dragon) and Partner (Progress, HTV) vehicles.

NASA is responsible for coordinating and scheduling USOS waste vehicle loading, using cargo loading maps developed by the appropriate Vehicle Partner (JAXA, Orbital and Space-X). NASA CMC is responsible for the development of CRS cargo loading maps generated from the chit approved USOS disposal lists.

Waste safety certification Specific breakdowns of internal NASA roles and responsibilities will be listed in a later section.

NASA is responsible for safety certification of NASA systems and payloads waste and USOS common waste.

ESA Roles and Responsibilities

WASTE PLANNING, STOWAGE, AND INTEGRATION

ESA is responsible for coordinating ESA waste planning, stowage, and integration with NASA. This is conducted via the WMR process, TWIG meetings, and Disposal chit reviews of USOS disposal lists.

Waste Safety Certification ESA is responsible for safety certification of ESA systems and payloads waste.

JAXA Roles and RESPONSIBILITIES

WASTE PLANNING, STOWAGE, AND INTEGRATION

JAXA is responsible for coordinating JAXA waste planning, stowage, and integration with NASA. This is conducted via the WMR process, TWIG meetings, and chit reviews of USOS disposal lists.

JAXA is responsible for development of HTV cargo loading maps generated from the chit approved USOS disposal lists.

WASTE SAFETY CERTIFICATION

JAXA is responsible for safety certification of JAXA systems and payloads waste.

CSA Roles and Responsibilities

WASTE PLANNING, STOWAGE, AND INTEGRATION

CSA is responsible for coordinating CSA waste planning, stowage, and integration with NASA. This is conducted via the WMR process, TWIG meetings, and chit reviews of USOS disposal lists.

WASTE SAFETY CERTIFICATION

CSA is responsible for safety certification of CSA systems and payloads waste.

waste safety and handling flight safety The bilateral NASA/ Roscosmos process for safety certification of waste on Progress vehicles can be found in SSP 50146 Attachment D “NASA/RSA General Principles and Requirements for ISS Cargo Safety”.

The process for HTV disposal cargo safety certification is found in JSX-2009059, Rev A. “HTV Cargo Safety Certification Process for Disposal”. For waste items being disposed of on Dragon or Cygnus, safety is reviewed by Cargo Mission Contract (CMC) to assess for any potential integrated hazards.

To help ensure timely disposal of cargo items and flexibility of vehicle assignment, it is recommended that hardware owners provide disposal safety data to the appropriate NASA or IP Safety Review Panel during initial hardware safety reviews so that baseline data is available for disposal at any time. The actual configuration of the hardware will need to be confirmed again prior to disposal to ensure the item has not had any on-orbit anomalies that impact the original certification and that it does not present any new hazards to the disposal vehicle.

In addition, the hardware provider must supply current safety certification data as required by the WMR, described in Section 5.5.4 for all waste items. The Waste Management Team (WMT) then uses the information on the WMR to assign items to the appropriate vehicle.

ground safety Ground safety reviews are conducted to protect personnel, facilities, equipment, other payloads, the flight crew, the general public, public and private property, and the environment from injury or damage during ground processing operations of waste. For more detailed information reference SSP 30599 Safety Review Process. For waste on returning vehicles, the requirements for the ground safety review process are given in the return manifest for the returning vehicle.

waste handling For USOS disposal items, the WMT includes waste handling requirements (as submitted by hardware owners via the WMR) and provides them to Mission Control Center - Houston (MCC-H) via disposal chits. The RSC-E Cargo Flow Group provides similar information to Mission Control Center - Moscow (MCC-M) for Russian Segment disposal hardware.

The USOS system manager(s) and Payload Developers (PD) are responsible for supporting the appropriate Flight Operations Directorate (FOD) representative in developing waste handling procedures, timeline requirements, and training and operational documentation for mission-specific and system-unique or payload-unique cases.

Russian payload specialists submit waste handling requirements to the Russian TWIG to dispose of waste resulting from experiments.

waste stowage A stowage volume for waste shall be designated. The waste stowage volume shall comply with internal volume constraints as defined in SSP 50261-01. The required volume shall be based on intervals between logistics vehicle undocking according to the Flight Program. The total waste generation will be stowed within the ISS habitable volume prior to loading into the Visiting Vehicle. This volume will be as far from the primary crew living and working locations as practical, and should not be used for the nominal stowage of other items.

For the USOS, the NASA Stowage Integration Working Group (SIWG) utilizes waste estimates in its planning process and factors in “actual” waste disposal volumes in the overall on-orbit stowage integration process. The SIWG supports and provides waste candidate recommendations to the TWIG, in an effort to manage USOS on-orbit stowage.

crew training JSC 36301, International Space Station Crew Training Catalog, defines overall crew training. The Stowage Management and ISS Stowage Hardware lessons provided by the Daily Operations and Crew Support Group (DOCS) reviews waste hardware and operational constraints.

It is provided to Expedition crews by the Flight Operations Directorate (FOD) Daily Operations Group. The Systems Integration Office provides the hardware for use in the class. The Waste Management team supports the Consumables training sessions per increment by providing an overview of the waste disposal process, expectations and expendable vehicle utilization scheduled for waste disposal planning.

The Gagarin Cosmonaut Training Center (GCTC) provides training to the Expedition crew for Russian-supplied hardware and disposal on Progress and Soyuz. A refresher is provided, as required, when significant changes have occurred. Training for the disposal of waste on HTV, Dragon and Cygnus vehicles is provided by NASA at the Johnson Space Center.

Payload developers with unique waste hardware provide training within their payload training sessions for those unique items.

Increment Disposal Planning WASTE MANAGEMENT Team Responsibilities The WMT is responsible for increment disposal planning through the development of disposal lists. Disposal lists are compilations of WMRs, which are coordinated between the WMT, FOD, CMC, Safety, and hardware providers. Flight specific disposal lists are released according to each flight’s Operational Interface Procedures (OIP) and approved using the chit system.

TRASH / WASTE INTEGRATION GROUP

TWIG participants include a NASA representative serving as chairman, members of the Waste Management Team, a Safety representative, an Inventory Stowage Officer, and hardware providers from various systems/organizations. The TWIG convenes bi-weekly with the primary function of coordinating waste management requirements.

JOINT WASTE MANAGEMENT TELECON

The WMT conducts a bi-monthly telecon with the Russian Waste Disposal Group to discuss on‑going waste assessments and analysis. This forum is used to exchange information, discuss and approve planning documentation, and answer questions between US and Russian waste management specialists. Telecons will be conducted with ESA and JAXA Cargo Integration Groups for any planning and discussion that affect ESA or JAXA cargo disposed on USOS vehicles as needed.

FLIGHT READINESS

The WMT provides inputs to the Visiting Vehicle Teams (VVT) for the integrated waste assessments as a requirement for certification for flight readiness. These results are reported to the Mission Integration and Operations Office by the VVTs.

INCREMENT DEFINITION AND REQUIREMENTS DOCUMENT

The post-flight disposal list reflects actual hardware status and is documented for all in the Increment Definition and Requirements Document (IDRD) Annex 1 for all vehicles to support Post- Increment Evaluation Reports.

WASTE IDENTIFICATION

All hardware targeted for disposal must have a WMR submitted prior to the items disposal unless that item is on an Easy Disposal List or Common Trash List. WMRs are necessary for the development of a flight disposal list. WMR data should be provided from hardware providers. Data required on the WMR includes mass, volume, part identifiers, and safety certification information. WMRs are available through the Management Information Database Automation System (MIDAS) suite of applications located at web address: http://iss‑www.jsc.nasa.gov:1532/midasagnt/plsql/midas_home_oas.

For Russian hardware to be disposed on USOS vehicles, Russia shall provide the US side with the same data, via a management fax to the Mission Integration and Operations Office Manager. Russia will provide their data in the form of a spreadsheet, as MIDAS is not available to the Russian counterparts.

For USOS equipment to be disposed of on Progress vehicles, NASA must submit data containing the mass, volume, and part identifier of the article and information on safety certification by sending a fax to the flight integration and flight operations office manager. Effort should be made, by NASA, to provide waste disposal not exceeding 1 CTBE in dimensions and 10 kg in mass. The data provided on the WMR as well as the data received from the Russian side will be used to determine what will be disposed on expendable vehicles.

POST INCREMENT CREW DEBRIEF

The WMT participates in the debrief activities of each increment crew to obtain information that will help planning subsequent increments. Crew concerns and lessons learned will be coordinated with the appropriate Visiting Vehicle organization.

ON-ORBIT Operations The following section describes on-orbit waste operations by addressing the two major components that are involved. The stowage aspects in Section 6.1, and labeling in Section 6.2.

STOWAGE

Waste STOWAGE locations A limited amount of waste can be re-stowed into volumes from which the hardware/consumables were removed.

In order to maintain a hygienic environment, waste and associated by-products should not be left onboard longer than necessary. Waste should not be stowed in the principle crew living and working areas.

The Stowage Integration Working Group is responsible for stowage of filled waste containers. The USOS stowage location is coordinated between the crew and ground teams.

used WASTE Container STOWAGE LOCATION Used waste containers should not be stowed next to food, clothing, hygiene, medical consumables, or medical equipment.

LABELING

Waste containers to be disposed on expendable vehicles do not require waste-specific labels to be applied on orbit.

All waste containers disposed on Dragon (Space-X) require a label identifying the waste type. Trash identification labels may be affixed to the containers via adhesive. Labeling may also be done by marking directly on the container with a sharpie. The Expedition crew will select the most appropriate method.

Bags should not be transferred to the Dragon vehicle without prior verification that a label is attached, S/N or B/C is affixed to the bag, or the bag is labeled with a sharpie.

Labeling standards for items on orbit are covered in SSP 50094, NASA/RSA Joint Specifications Standards Document for the ISS Russian Segment.

HAZARDOUS WASTE LABELING

For hazardous waste, the Trash Identification Label on the outermost containment barrier shall identify all battery (BA) hazards, biological/biomedical (BB) hazards, sharp (SH) hazards, chemical (CH) hazards, and/or radioactive (RA) hazards. Chemical hazards are identified by circling the chemical logo on the label and by indicating the payload or system that the chemical waste came from. Radiation hazards are identified by circling the radiation logo on the label and by annotating the isotope and date that the radiation hazard was produced.

The containment packaging and labels are provided by the System/Payload Developer and stored with their hardware.

TOXICITY IDENTIFICATION

When multiple types of hazardous waste are accumulated in a single hazardous waste container, the outermost container label shall indicate the highest level of toxicity contained (0-4).

waste disposal planning All waste is removed from the ISS via expendable vehicles: HTV, Cygnus, or Progress. Trash can also be removed by the return vehicles, Dragon and Soyuz, but these vehicles are preferentially used for return cargo. The following section defines waste disposal priorities, manifest planning for waste disposal, and vehicle constraints or requirements.

PRIORITIZATION FOR REMOVAL

In order to minimize the quantity of hazardous waste on ISS, the nominal priority for removal of waste is as follows:

DISPOSAL MANIFEST PLANNING

The initial step in this process is the identification of waste to be disposed. Russia and the USOS are each responsible for the disposal of their own Common and non-common waste. Use of expendable vehicles is preferred by the ISS Program for waste disposal. Crew common waste can be disposed on any vehicle (Soyuz, Progress, HTV, Cygnus, or Dragon) in any of the waste containers as defined in Table 4.1.1-1. Technical teams for the RS and the USOS will work together to develop a trash plan for each year and will utilize all vehicles available for removal of trash to best provide the capability for the partnership. Regardless of the actual amount of trash removed on each partner’s vehicle at the end of the year, no compensation or debt will be due either side as negotiated by a separate agreement.

USOS Waste disposal on russian vehicles General information and requirements on the Progress/Soyuz vehicles, as well as cargo integration schedules and milestones are provided in document П32928-103, Requirements for International Partner Cargo Transported on Russian Progress and Vehicles. To facilitate the waste integration process on the Progress vehicles, the US side should submit a request to RSC-E to include the waste in the manifest no later than six weeks before vehicle undocking. The template schedule is documented in SSP 50489, ISS Mission Integration Template. The possibility of disposing of US wastes on the Progress is determined by the results of a review of the dimensional installation drawings and safety data.

The Russian Safety Group coordinates with US Safety as required during the process of review of the safety of waste hardware for disposal on Progress vehicles.

PROGRESS WASTE DISPOSAL

The Progress vehicle is one of the primary means of removing waste from the ISS.

Waste may be accommodated in the Progress cargo compartment and in the Rodnik system tanks. In the Rodnik system tanks, only liquid waste may be stowed. Waste stowed in the cargo compartment must be firmly secured to prevent movement inside the Progress cargo compartment.

A volume of approximately 6 cubic meters (m3) is available in the cargo compartment for waste stowage. The Rodnik tanks have approximately 420 liters of liquid waste stowage volume available. Therefore, assessments assume up to 19 EDVs may be dumped into these Rodnik tanks and reused. Coordination of cargo compartment waste is coordinated between the RS and USOS technical waste teams.

The total mass of waste to be removed depends on the propellant margin in the vehicle propulsion system tanks, the vehicle constraints associated with mass properties and the vehicle flight plan after undocking from the ISS. In the cargo compartment, the mass can be as much as 1700 kilograms (kg).

Soyuz waste disposal A volume of approximately 1 m3 is available in the Soyuz vehicle for waste stowage with the mass of all waste to be disposed not exceeding 100 kg.

Tanks with liquid that are stowed in the Soyuz vehicles should remain sealed during orbital module depressurization. Orbital module depressurization occurs prior to separation from the Descent module.

htv Waste Disposal General information on the HTV and the requirements levied against documentation to be submitted are contained in JHX-2008174, HTV Cargo Integration Plan. To facilitate the waste integration process on HTV, the WMT will submit disposal data to the JAXA HTV Cargo Integration Group. Reference “Figure I-2 HTV Waste Management Process” for detailed flow of disposal operations.

Cygnus Waste Disposal IMC/Visiting Vehicle Team (VVT) is responsible for the delivery of disposal data to CIPHER, based on the approved IMC/Waste Management Team (WMT) Disposal List CHITs IMC/VVT/CMC is responsible for developing and releasing “A” chits including the integrated bag level disposal packing plan spreadsheet that includes a list of the outermost bags and the roll-up mass of their contents, the Mass Properties Report (MPR), and Haz Tox data.). Orbital (MCC-Dulles CIPHER) is responsible for the Waste Cargo Maps (graphic depiction of bag locations in the Cygnus). CIPHER will coordinate with the ISOs before responding to chits with updated Waste Cargo Maps. Reference “Figure I-1 Cygnus Waste Management Process” for detailed flow of disposal operations.

Dragon Waste Disposal <TBD 7-1> Disposal of US hardware on Dragon (Space-X) vehicles will follow the manifest process where MRs will be written for returning hardware trash.
